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 -- the same scope as Fillout's Make integration.

How It Works

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

API Endpoints (OpnForm Side)

The app calls these endpoints on the OpnForm API (authenticated via Sanctum API token):

Endpoint	Method	Purpose
/external/make/validate	GET	Validate API key, return user info
/external/make/workspaces	GET	List user's workspaces
/external/make/forms?workspace_id=X	GET	List forms in a workspace
/external/make/webhook	POST	Register webhook (attach)
/external/make/webhook	DELETE	Unregister webhook (detach)
/external/make/submissions/recent?form_id=X	GET	Poll sample data for structure detection

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
