API - Related records

[Stefan]

Hi!

I tried to link an n:1 resp. 1:n relationship vie API as described in the docs https://docs.espocrm.com/development...ionships/#link

But this doesn't work:

WARNING: (403) Only manyMany, hasMany & hasChildren relations are allowed.

Is there another way to link them or am I doing something wrong?

I would appreciate any help!

Hi,

It's in the release notes https://github.com/espocrm/espocrm/releases/tag/8.1.0, https://github.com/espocrm/espocrm/issues/2882. There were reasons to do it, it was not supposed to have this ability from the beginning, but we had it that was a mistake that led us to problems.

As it's stated in the issue, you have to use a regular PUT request. Updating a record by setting an ID of the foreign record. It's literally the same what the method did internally before.

PUT https://your_url/api/v1/EntityType/recordId

{
    "linkId": "foreignRecordId"
}

Where 'link', is the link name.

As an alternative, you can create a custom API endpoint.

The documentation does not stipulate n:1 support. It states that it's possible to pass a single ID instead of array of IDs.

Thanks yuri. Didn't know I can just use a PUT request. That helped me a lot!
