This webhook is called when checking a product’s availability during proposal creation. The request URL contains the search parameters start, end, and an optional attendees. The body of the POST request that we’ll call contains the following fields:
Check Availability for a product
{
  id: string;
  created: number;
  type: 'content.availability';
  integration: IntegrationSessionData;
  integrationBlockSource: {
    integrationId: number;
    uniqueId: string;
    metadata: Record<string, unknown>;
  },
  row?: {
    integration?: Record<string, unknown>;
    quantity?: number;
  }
}
The response we expect from your side is a json object with the following format:
Response
{
  data: {
    available?: boolean;
    quantity?: number;
  }
}
If availability is not applicable for a specific product, return an object with an empty data field. Otherwise you can either set available or quantity, depending on if it’s a single resource, or numbered. Once a block has been added to a proposal and opened in the sidebar, the row property will be included in the call.
