Hi
How to create an account to document link?
POST URL: /Api/V8/module/Accounts/{{ id }}/relationships
DATA:
{
"data":[
{
"type": "Documents",
"id": "{{ id }}"
}
]
}
RESPONSE:
{
"errors": {
"status": 400,
"title": null,
"detail": "The option \"0\" does not exist. Defined options are: \"id\", \"type\"."
}
}
Any help would be appreciated.
Cheers
Steve
Hi,
it seems like you’re using the same variable for both Ids ( {{id}} ). Within the URL, you should provide the respective account id, within the json, you provide the document id.

Sorry, my bad! I am actually using two different ID’s just my crap example

I guess your [ ] brackets are wrong 
Hi @Sheathy,
Welcome to the Community! 
Quick tip for the forums you can surround top and bottom with ``` or inline on both sides with ` which produces code boxes and make it easier to read. I’ve updated your post to include these
So to add a document to the subpanel of and account (I.e relate them)
Post
/V8/module/Accounts/ID_OF_ACCOUNT_RECORD/relationships
Request Body
{
"data": {
"type": "Documents",
"id": "ID_OF_DOCUMENT_RECORD"
}
}
And you should get a response like this (Includes example IDs here)
{
"meta": {
"message": "Document with id eba910c5-cf4d-b31c-906c-5f9943cae193 has been added to Account with id 1a8d45ae-1216-6199-97bf-5f92d46f0a50"
},
"data": []
}
Tip if you haven’t already, upload the swagger found here
Api/docs/swagger/swagger.json
to a site like https://editor.swagger.io/
Which gives you some easier to use API docs
Any questions let me know 
Sorted, thanks for all your help.
Cheers
Steve
