Instagram API Automation for Software Publishers

DMA

Our solution is built in line with the Digital Markets Act (DMA). User profiles are never stored or scraped, and our API focuses exclusively on enabling messaging interoperability. Clients are expected to comply with the terms of each provider.

Instagram API is now a strategic messaging tool. With the right API, you can automate DMs, sync conversations, and trigger sequences inside your CRM or ATS.

This guide shows how to do it with Unipile’s unified API, offering a single gateway to Instagram, LinkedIn, WhatsApp, and more. Please note that Unipile is not a Meta Partner, and all usage must respect Meta’s rules.

Instagram API Automation: What Developers Need to Know

APIs (Application Programming Interfaces) let your app communicate with external services. Endpoints are specific functions you can call to perform actions like sending a message, receiving replies, or listing conversations.

Instagram API Basics: What Developers Need to Know

Business account and permissions

Instagram automation is only possible for business accounts connected to a Facebook Page. You’ll need:
– An Instagram Business Account
– A linked Facebook Page
– Approved app permissions from Meta for pages_messaging, instagram_basic, and instagram_manage_mess

Token-based access

You authenticate via access tokens (short or long-lived), which allow your software to:
– Retrieve messages
– Send replies
– Monitor message status (delivered, seen)

However, Meta limits message automation significantly—you cannot initiate DMs without user interaction. This is where Unipile’s API opens up new doors.

CRM Automation

  • Log every Instagram DM to the lead’s contact card

  • Auto-reply when a message is received

  • Launch a pre-built drip sequence after message #1

ATS Integration

  • Monitor inbound Instagram messages from candidates

  • Trigger follow-up tasks or emails based on IG replies

  • Sync all messages to the hiring pipeline

Outreach Software

  • Launch personalized Instagram DM campaigns

  • Trigger messages via automation sequences

  • Track message views, replies, and conversions

API Endpoints for Instagram Automation

Here are key endpoints to power Instagram automation:

POST /api/v1/messages Send an Instagram message (text, image, voice)
GET /api/v1/chats Retrieve all IG message threads
POST /api/v1/webhooks Subscribe to events like new message, reply, reaction

API Token & DSN Setup

Every request needs a valid token and your DSN (data source name). These are easily managed from Unipile’s developer dashboard.

Use the SDKs

Available in Node.js, PHP, and via cURL/REST. You can:

  • Test endpoints instantly
  • Skip OAuth complexity

  • Rely on secure hosted flows

Live Testing in the Docs

Unipile provides interactive documentation where you can test any endpoint without code. Just paste your DSN + Token.

Unified Inbox: Centralize Instagram Conversations in Real-Time

Instagram DM integration in app interface

One of the biggest pain points in integrating Instagram into CRMs or ATS platforms is message fragmentation. Unipile solves this with its unified inbox, allowing you to:

  • Sync Instagram DMs in real-time across multiple user accounts
  • View message history from Instagram alongside LinkedIn, Gmail, WhatsApp, and others
  • Reply to messages directly within your app, without switching context

This creates a seamless experience for recruiters, sales reps, or support agents who no longer need to juggle multiple tabs or tools.

With Unipile, Instagram becomes part of a broader engagement strategy where every channel is tracked and accessible in one place, enabling better follow-ups, team collaboration, and user satisfaction.

Integrating Instagram messaging into your product shouldn’t mean navigating Meta’s limitations. Unipile’s unified API offers a faster, simpler, and more scalable alternative, designed for developers who want to launch messaging features without hitting roadblocks.

Connect an Instagram Account Using Unipile

To authenticate an Instagram account, users need to provide their Instagram username and password directly. Currently, login through Facebook credentials is not supported for this flow.

How to Authenticate

Use a POST request to Unipile’s API to connect the account. This can also be done via one of the available SDK methods.

Link an Instagram Account 
    
curl --request POST 
     --url https://{YOUR_DSN}/api/v1/accounts 
     --header 'X-API-KEY: {YOUR_ACCESS_TOKEN}' 
     --header 'accept: application/json' 
     --header 'content-type: application/json' 
     --data '
{
  "provider": "INSTAGRAM",
  "username": "unipile",
  "password": "********"
}
'

Managing 2FA Checkpoints

When two-factor authentication is enabled on an Instagram account, Unipile will return a 202 Accepted status with a checkpoint object.

    
{
  "object": "Checkpoint",
  "account_id": "098dez89d",
  "checkpoint": {
    "type": "2FA"
  }
}

In this case, a new Authentication Intent starts. This intent last 5 minutes and checkpoints must be solved in this time frame.

Completing 2FA Verification

To resolve a two-factor authentication (2FA) challenge, send a POST request to Unipile’s dedicated checkpoint endpoint. Use the account_id received from the initial connection attempt and provide the code sent by Instagram.

    
curl --request POST 
     --url https://{YOUR_DSN}/api/v1/accounts/checkpoint 
     --header 'X-API-KEY: {YOUR_ACCESS_TOKEN}' 
     --header 'accept: application/json' 
     --header 'content-type: application/json' 
     --data '
{
  "provider": "INSTAGRAM",
  "account_id": "098dez89d",
  "code": "******"
}
'

Don’t Miss the Timeout Window

Be aware that you only have 5 minutes to complete the 2FA validation process. If this time limit is exceeded, your first attempt will return a 408 Request Timeout, and any further retries will result in a 400 Bad Request, meaning the session has expired and must be restarted from the beginning.
