Connection(many to many) record not being updated for multiple connections using API

[MikeBeatti08620]

Hi,

I am trying to update a connected record which has many to many relation with another object but it fails to update for multiple using API

there is a similar question but that solution doesn’t work for me either

Add ANOTHER connection using the API and jQuery

I finally figured it out so am posting for anyone else who needs to ADD CONNECTIONS to a field that already has some connections in it: It was very confusing because what would come OUT OF the existing array was not the same way that I needed to put it back in! I had to Read the existing connections from the raw connection field Extract ONLY the id from each record Put each existing ID into a temporary array Add the new ID to the temporary array Send the temporary array in my JSON object and…

so the scenario is

object_1 and object_2 has many to to many relation, I am maintaining the relation in object_1, so when I try to update object_1 through API, it works for a single record but for multiple it doesn’t.

to explain through code

object_1[field_2]=[id1] works
but
object_1[field_2]=[id1,id2] doesn’t work

it saves field_2 as blank.
