Indexer Webhooks

When you create an event indexer under a project, you can provide an optional Webhook Location:

If this property is set, the indexer will make a POST request to the specified URL with all matching events that occur on chain after the indexer was created with the following request body:

  "id": <event id, string hash>,
  "graffleProjectId": <your project id, guid>,
  "graffleCompanyId": <your company id, guid>,
  "flowEventId": <event id on flow chain, ex: A.921ea449dffec68a.FlovatarMarketplace.FlovatarComponentForSale>,
  "graffleEventToken": <token representing this indexer, guid>,
  "blockHeight": <block height on flow chain that event occurred at>,
  "eventDate": <DateTimeOffset of when the event occurred>,
  "createdAt": <DateTimeOffset of when the event was recorded>,
  "blockEventData": {
    <object representing the event data on chain>
  "webHook": <your webhook url>,
  "flowTransactionId": <transaction id on flow chain>
  "transactionIndex": <zero-based index of the transaction within the block>
  "eventIndex": <zero-based index of the event within the transaction>
  "collectionId": <currently unused>
  "graffleWebHookDataId": <internal graffle id>
