TL;DR: An appointment-scheduling flow via Instagram DM automatically sends every prospect who comments "TERMIN" or sends you a DM a service selection, the appropriate booking link (Calendly, Cal.com, etc.) and a reminder before the appointment. In this copy-paste guide you build the complete flow in under 10 minutes with replient.ai. GDPR-compliant, officially supported by Meta, let people book appointments around the clock.
Last year we had an onboarding call with a photographer from Munich. She had 12,000 followers on Instagram, posted wedding photos regularly, and under almost every reel were comments like "Are you still free in October?" or "How much does a shoot cost?". Her answer: type copy-paste DMs, insert a Calendly link, and hope people book before they keep scrolling. On good days she managed 15 DMs manually, but 30 more went unanswered. "I know I'm missing bookings, but I don't have time to type DMs all day," she said on the call. My brother Markus then said, "That's exactly the point: when someone asks under a reel if you're available, the intent is at its highest. And then you make them wait six hours." Today I'll show you the flow that completely eliminates this bottleneck.
Why Instagram is the ideal booking channel for service providers
Instagram is no longer just an inspiration platform. For coaches, photographers, hairdressers and consultants, Instagram is the place where potential customers first make contact, not by email, not via a contact form, but by DM or comment.
The problem: Most service providers treat Instagram DMs like emails. They check them morning and evening, type responses manually, and then at some point send a booking link. According to Salesforce State of the Connected Customer 73% of consumers expect companies to understand their individual needs, and 83% expect an immediate response. A DM that sits unanswered for 6 hours is in most cases a lost booking.
Instagram DMs outperform email in every relevant metric:
- 90% open rate for DMs vs. ~20% for emails. Someone who sends you a DM will almost certainly read your reply (LeadResponse, 2026).
- 391% higher conversion when answered within 60 seconds. No one can reply to 30 DMs in 60 seconds at the same time, an automation can (LeadResponse, 2026).
- Instagram has over 2 billion active monthly users (Statista, 2025), your customers are there.
The complete booking flow: what we're building today
The flow consists of five building blocks that you assemble in replient.ai via drag and drop:
- Trigger: comment "TERMIN" under your post or inbound DM with a keyword
- Send Message: Personalized welcome DM
- Ask Question: service selection via quick-reply buttons
- Send Link, Trackable Calendly/Cal.com link for the appropriate service
- Time Delay + Reminder, Reminder before the appointment
Block 1: Trigger, "APPOINTMENT" as entry signal
Two trigger options make sense, depending on how your customers contact you:
Option A: Comment trigger (Comment-to-DM)
Select the "Someone comments on your post" trigger in replient.ai and configure:
- Post-Scope:"Any post" or "Specific post" (e.g. your booking reel)
- Keyword:"APPOINTMENT" (or "BOOK", "BOOK APPOINTMENT")
- Matching: Case-insensitive, whether someone writes "Appointment", "appointment" or "APPOINTMENT", the flow starts
Option B: Inbound DM trigger
Select "Someone sends you a DM" with a keyword filter such as "APPOINTMENT", "BOOK" or "Appointment". This way you catch direct messages too, not just comments.
Pro tip: You can run both options as two separate automations in parallel. The comment option catches public inquiries, the DM option private ones. In the replient.ai trigger setup simply add multiple keywords to the filter list.
In code, replient.ai uses the post_comments and incoming_dm trigger with stored keywords[]. Matching is case-insensitive and checks with .includes() whether the keyword occurs in the text.
Block 2: Send Message, personalized greeting
As soon as someone triggers, the first DM goes out. The "Send Message" step sends a personal message:
Copy-paste template:Hey {{contact.username}}, great that you want to book an appointment! I'll show you my available times in a moment. One quick question before that:
Personalization: In replient.ai these variables are available to you:
-
{{contact.username}}: Instagram username -
{{contact.name}}: Display name -
{{contact.followerCount}}: Follower count -
{{automation.currentDateTime}}: Current date and time
Personalization makes the difference. According to Salesforce, 73% of consumers expect companies to understand their individual needs. "Hey @sarah.vienna" feels personal, a generic reply does not.
Block 3: Ask Question, service selection via button
The decisive step that sets this flow apart from a simple link send: the service selection. In the "Ask Question" step you give the customer quick-reply buttons to choose their desired service.
Copy-paste template (question):Which appointment would you like to book?
Button options (photographer example):- Wedding shoot - Portrait shoot - Business photos
Button options (coach example):- Introductory call (free) - 1:1 coaching - Group coaching
Configuration in the builder:
- Up to 13 quick-reply options (max. 20 characters per option)
- Each option creates its own branch in the flow
- Timeout branch: 'If no response after X days'
Each button option leads to a separate branch, and therefore to a different booking link. A photographer sends a different Calendly link for "wedding shoot" than for "business photos". A coach directs the free introductory call to a 30-minute slot, and 1:1 coaching to a 60-minute slot.
Why the preselection is worth its weight in gold: Without a service selection you get bookings on the wrong calendar. A wedding photographer who offers a 30-minute slot for an introductory call and a whole Saturday for a shoot needs two different Calendly events. The Ask Question branching logic in replient.ai solves this elegantly.
Block 4: Send Link, Calendly/Cal.com integration
Depending on the chosen service the flow sends a different booking link. The "Send Link" step automatically creates a tracked short link that forwards to your booking page.
How to configure the Send Link step:
- Provide booking URL (Calendly, Cal.com, Acuity Scheduling, SimplyBook.me, or your own booking tool)
- Define button text (e.g. "Book appointment now")
- Optional: subtitle with context (e.g. "Wedding shoot · 2h · from 890 EUR")
Branching after click: The Send Link step offers two automatic branches:
- Link clicked→ Flow continues (schedule a reminder)
- Link not clicked after X days→ Send follow-up DM
The click-tracking link automatically captures how many prospects actually opened the booking link. You can see it directly in the replient.ai analytics.
Tool integrations for the booking page:
| Tool | Ideal for | Price (from) |
|---|---|---|
| Calendly | Coaches, consultants, B2B | Free (1 event type) |
| Cal.com | Developers, open source | Free (self-hosted) |
| Acuity Scheduling | Salons, therapists | $20/month |
| SimplyBook.me | Hairdressers, studios | Free (50 bookings) |
| Google Calendar links | Minimalist | For free |
Module 5: Time Delay + Reminder DM
The last module reduces no-shows. You set a time delay and send a reminder DM before the appointment:
Copy-paste template (Reminder):Hey {{contact.username}}, quick reminder: your appointment is tomorrow! If you need to reschedule, just message me here. I'm looking forward to seeing you!
Configuration:
-
duration: 1 (e.g. 1 day before the appointment) -
unit:days(Options: minutes, hours, days)
No-shows are a real problem for service providers. According to the Zenoti Beauty & Wellness Benchmark Report (2025), the average no-show and cancellation rate in the beauty sector is around 21%. Automated reminders reduce no-shows to under 5%, which corresponds to a reduction of up to 70% (Shortcuts Software, 2025). An Instagram DM has the advantage that, with about a 90% open rate, it is read far more often than an SMS or email.
Manual vs Automation: The direct comparison
What happens without automation? You type. You forget DMs. You lose bookings. Here is the comparison:
My brother Markus manages several service brands as a performance marketer. His running gag: "They post a reel at 8 pm, inquiries come at 10 pm, and by 8 am the intent is gone." This timing problem is exactly what automation solves, it replies in seconds even on Sundays at 11 pm.
GDPR, Meta policies and security
Three questions always come up with appointment scheduling flows:
Is this GDPR compliant?
Yes. replient.ai is GDPR-compliant as a European company and processes all data on EU servers. The DM automation uses the official Meta Graph API, no scraping, no gray area. Important: Do not ask for sensitive health data in the flow (Art. 9 GDPR). The appointment booking itself takes place on the external booking page, not in the DM.
Does Meta allow this kind of automation?
Yes. replient.ai is an official Meta Business Partner. The automation uses the Messenger Platform API, which is designed specifically for this use case. As long as you do not send unwanted mass DMs (which the flow does not do, it only responds to user-initiated interactions), you are within Meta's policies.
What about appointment booking tools?
The flow sends a link, the actual booking takes place on Calendly, Cal.com, or your booking tool. The respective tool's privacy policy applies there. replient.ai does not store booking data, only the DM interaction.
Who this flow is for
This appointment scheduling flow works for any service provider who acquires customers via Instagram:
- Photographers, automatically turn shoot inquiries into bookings
- Coaches & consultants, allow booking of initial consultations and 1:1 sessions
- Hairdressers & beauty studios, offer appointment slots around the clock
- Personal trainers, trial training sessions and consultation appointments
- Therapists & naturopaths, initial appointments and follow-ups
- Agencies, strategy calls and audits
The common denominator: your customers discover you on Instagram, have immediate intent, and you need a way to convert that intent into a booking, without typing DMs manually.

Frequently Asked Questions
How can I set up automatic DMs on Instagram?
With replient.ai you create a DM automation flow in under 10 minutes: choose a trigger (comment or inbound DM), add action steps (Send Message, Ask Question, Send Link), and activate. The flow automatically responds to any interaction that contains your keyword.
Can I send different booking links for different services?
Yes. The Ask Question step offers quick-reply buttons, each leading to its own branch. Each branch can contain a different booking link, for example Calendly link A for coaching and Calendly link B for workshops.
Does this also work with my existing booking tool?
Yes. The flow sends a trackable link to any URL. Whether Calendly, Cal.com, Acuity, SimplyBook.me, or your own booking system, as long as it has a URL, it works.
Is Instagram DM automation allowed by Meta?
Yes. replient.ai uses the official Meta Graph API as a certified Meta Business Partner. The automation responds only to user-initiated interactions and does not violate Meta's policies.
How can I reduce no-shows with the flow?
The Time Delay step sends a reminder DM before the appointment, for example 24 hours beforehand. DMs have an open rate of about 90%, significantly higher than SMS or email reminders. That alone can reduce no-shows by up to 40%.
Do you need an Instagram Business account?
Yes. The Meta Graph API that replient.ai uses requires an Instagram Business or Creator account. A private profile cannot be connected to DM automations.
