Business Central, POST request with BLOB

Posted on by MG-04060224-0

I create custom table with blob field and API for that table.
If I send POST request without blob field (not null, removed key, value pair from json), it creates new record without any problem.

Problem is, if I send it with blob field it returns this error
400:
{

/error/: {

/code/: /BadRequest/,

/message/: /A body must be provided to the request. CorrelationId: 16a11edd-0c4b-4b11-bd26-be3a072d37c3./

}

I have tried
1. /blobfield/: null
2. /blobfield/: /some base 64 string/
3. /blobfield/: {}
4. /blobfield/: { /Length/:0, /IsDefault/:true }

How to send blob via POST request to business central? Or is there any better way to save file in business central with API?

Good morning.

I'd create a boundaction in the API page, send the BLOB content as Base64, and in the BoundAction do the code required to convert from base64 and assign it to the BLOB field you need to.
