Your customers publish without leaving the experience you built.
Image, mixed carousel, Reel with cover and Story. Direct upload or by URL, validated before it reaches Meta.
Pick the instant with an explicit offset. Reschedule or cancel through the API until sending starts.
Receive signed post.scheduled, post.published and post.failed events. Temporary failures are retried.
Query performance and use interactions in your SaaS processes.
Views, reach, likes, saves, and available account metrics straight from Meta, cached for five minutes. Availability varies by format and account.
List, reply to, hide and delete comments on published posts.
Read the account's conversations and reply within Meta's 24-hour window.
Capture validated answers and deliver them to the system already serving your customer.
Set keywords per post. The account sends an initial private reply to the comment and, optionally, a public reply. The flow continues when the person responds.
Messages, questions with buttons and capture of email, phone, number or text, with validation and per-node timeouts.
Every step and the end of every run reach your webhook with the collected data.

HOW TO INTEGRATE
Sign in to the dashboard, create a key and send it in the header of every call. The dashboard is where you watch what the API does.
Request the authorization URL, redirect the account owner, and receive them back in your app. Postmatic refreshes tokens and notifies you when a new authorization is needed.
Publish content, query metrics, and build flows through the API. Configure your webhook to receive publishing and automation execution events.
CHANNELS
We plan to expand Postmatic to other platforms. Available features will depend on each platform’s capabilities and permissions.
First available channel
Meta tokens are encrypted in the database and never appear in the API or the dashboard.
Meta OAuth, tokens encrypted at rest, automatic refresh, and notifications when a new authorization is needed. Account health is available in the dashboard and API.
Meta's data deletion callback and a route to erase the data of anyone who answered a flow.
Name, text and answers of people who engage are anonymized after 90 days.
Data from connected accounts is used only to run your integration.
FREQUENTLY ASKED QUESTIONS
Yes. Each Instagram account connects through Meta’s OAuth, from your app or the dashboard. It must be a professional or creator account. Postmatic refreshes tokens and notifies you when the owner needs to authorize the account again.
To integrate with your product, yes: the API is HTTP with JSON and has examples in cURL, Node and Python. The dashboard lets you connect accounts, publish and follow posts without code.
An automation can send an initial private reply to a comment, once per comment and up to seven days after it. To continue, the person must respond; subsequent messages follow the 24-hour window after their latest reply. Outside automations, the messages API only replies to conversations with a prior message from that person.
They reach your system through the automation.run event and are available in the API. Names, text, and answers are anonymized after 90 days. A route can erase captured data; for a definitive deletion request, pause the automation before using it.
Postmatic delivers the data through an event. Your application receives that event and performs actions such as creating or updating a contact in the CRM.
You receive post.failed with the error code and message, and can check it in the dashboard or the API. Temporary failures are retried automatically; authorization or content problems require reconnecting the account or fixing the post.
Instagram is the first available channel. LinkedIn, X/Twitter, and TikTok are planned expansion, with no date set.
Capabilities vary by platform. We document what each integration supports.
Current limits: up to 10 items and 5 accounts per post; captions up to 2,200 characters; Reels up to 15 min and 300 MB; scheduling from 1 minute to 75 days ahead; flows with up to 20 nodes.
Nothing during the initial phase, with usage limits and no credit card. Plans will be announced before any charge.
