Custom Object Limits using API

[Darshil_Shah1]

Is there any capping on the maximum number of records that could be added in a Custom Object in a single POST API call (/rest/v1/customobjects/{name}.json) for any kind of marketo subscription (Licensed/Sandbox)?

Also I have the same question for the retrieval of the custom object records using the same endpoint (rest/v1/customobjects/{name}.json) - GET Method. Thanks 🙂

I think you are referring to the following endpoint when you say you are trying to retrieve the records:

https://developers.marketo.com/rest-api/endpoint-reference/lead-database-endpoint-reference/#!/Custo...

If so, it will return you 300 records max in one go.

Unfortunately, there is no bulk extract API support for custom objects.

For creating records, in the official document they haven't mentioned any limit but I would wonder if you can pass more than 300 records in one batch. If you have lots of data to input in Marketo, I would suggest to look at the bulk import API for custom object here:
https://developers.marketo.com/rest-api/endpoint-reference/lead-database-endpoint-reference/#!/Bulk_...

There are some limits for bulk import:

• Max Concurrent Import Jobs: 2
• Max Queued Import Jobs (inclusive of currently importing jobs): 10
• Max Size of Import File: 10 MB

Thanks Amit this helps. Since its not mentioned in the docs wrt no. Of records I believe for the POST request the capping would be based on the size of payload data and not the record counts.
