Correct answer & explanation
✓
Verify that the primary key field is explicitly mapped and populated with unique values in every incoming JSON batch object.
The Ingestion API requires a defined primary key in the schema definition payload, and each incoming record must supply a unique value for this designated primary key field to prevent payload rejection.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Check that the primary key is hashed using MD5 before sending the payload to the Data Cloud endpoint.
Why it's wrong here
Hashing primary keys is not required by the Ingestion API.

Ensure that the primary key field is designated as nullable within the connected source object schema.
Why it's wrong here
Primary key fields cannot be nullable.
