This endpoint must be called after every transaction submission to save the transaction hash to an execution. If it fails to save, that likely means the transaction itself has failed.

​
Overview

After a consumer submits a transaction using calldata from the evaluations endpoint, you must save the transaction hash here. This creates or updates an execution to track the user’s progress through the trail.

​
Execution Types

  • “latest” (default): Adds to the most recent execution, or creates one if none exists
  • “new”: Always creates a new execution
  • “manual”: Adds to a specific execution by ID

​
Execution Behavior

When submitting a transaction:
  • “new”: Creates a new execution and adds the transaction as step 1
  • “latest”: Adds to existing “latest” execution, or creates one if none exists
  • If a transaction already exists for this step in the latest execution, it “forks” to create a new execution
  • “manual”: Adds to the specified execution ID

​
Request Body

{
  "nodeId": "uuid-of-primary-node-for-step",
  "transactionHash": "0x...",
  "walletAddress": "0x...",
  "execution": { 
    "type": "latest" | "new" | "manual",
    "executionId": "uuid" // only required for "manual" type
  }
}

​
Important Notes

  • Do NOT create executions beforehand - let this endpoint handle creation
  • Usually use “latest” execution type unless user selects a different execution
  • API will return an error if the transaction hash is invalid or failed
  • You can skip a step by sending a nil transaction hash: 0x0000000000000000000000000000000000000000000000000000000000000000

​
Error Handling

If this endpoint fails, the transaction itself likely failed. Always return a transaction error to the consumer with the hash for investigation.

​
Workflow

  1. Get transaction calldata from evaluations endpoint
  2. User signs and submits transaction
  3. Immediately call this endpoint with the transaction hash
  4. Handle any errors appropriately
