Copy your organization ID and each venue ID from Overview when you wire up the API or widgets -- you'll paste them into requests, embed attributes, and support tickets.
Use the Developers area when you're integrating TablelistPro with your own systems: Webhooks for real-time event delivery, API Keys for authenticated REST access, and Widgets to embed booking and events on your site.
Open the sidebar, click Organization, then Developers. Start from Overview for shortcuts to Webhooks, API Keys, and Widgets, or open those pages directly from the same section.
On Overview, you'll see Organization & venue IDs -- your organization id plus each venue id (the same values people mean when they ask for a venue id or org id). You'll use these ids in API requests and when configuring embeddable widgets. For endpoint and schema details, head to the TablelistPro API reference.
For step-by-step setup of REST credentials, see API keys. For webhook endpoints and events, see Webhooks.
For building and installing widgets (themes, embed code, and the JavaScript SDK), see Adding Widgets and the widget-specific articles in the Widgets section of these docs.
