OpnForm Make.com Custom App

Configuration files for the OpnForm custom app on Make.com (formerly Integromat).

This app provides a "Watch New Submissions" instant trigger so Make users can automate workflows whenever a form receives a submission.

How It Works

1. User searches "OpnForm" in Make's module picker
2. Creates a connection using their OpnForm API key (Sanctum token)
3. Selects a workspace and form from dynamic dropdowns
4. Make auto-registers a webhook via OpnForm's standard integration API
5. On each form submission, OpnForm POSTs data to Make's webhook
6. When the scenario is deleted, Make auto-unregisters the webhook

Architecture

This integration follows the same lightweight pattern as OpnForm's Activepieces integration. It uses OpnForm's existing /open/* API -- no dedicated Make endpoints are needed.

API Endpoints Used

All endpoints are part of OpnForm's existing API, authenticated via Bearer token (Sanctum):

Endpoint	Method	Purpose
/open/workspaces	GET	Validate API key + list workspaces
/open/workspaces/{id}/forms	GET	List forms (paginated, 10/page)
/open/forms/{id}/integrations	POST	Create Make integration (attach webhook)
/open/forms/{id}/integrations/{integrationId}	DELETE	Remove integration (detach webhook)

Setup in Make

Docs: developers.make.com/custom-apps-documentation

Option A: Make Web Interface

1. Log in to Make.com
2. In the left sidebar, click Custom Apps (click "More" if not visible)
3. Click + Create app and name it opnform (label: "OpnForm")
4. Configure the Connection using connection/parameters.json and connection/communication.json
5. Create a Webhook (dedicated + attached) using webhook/ configs
6. Create an Instant Trigger module "Watch New Submissions" using modules/watchNewSubmissions/ configs
7. Create RPCs listWorkspaces and listForms using rpcs/ configs
8. Test end-to-end with a real OpnForm API key
9. Submit for marketplace review (review takes ~4-6 weeks)

Option B: VS Code Extension

1. Install the Make Apps Editor VS Code extension
2. Generate a Make API key with sdk-apps scopes from your Make account
3. Connect the extension and sync the configs from this repo
4. Edit and test locally, then push changes to Make
