Find a customer's accountID

[FrancoB]

Hello everyone,
I wanted to ask for confirmation about a problem I'm having:
Through automation, I update a custom Email field by entering an email address that is generally already present in the project's Customers (portal access) or is a Jira user.
Now, in the automation, I would also like to be able to enter request participants, and since there may already be some present, I thought I would do an update via JSON using the account ID, as when I try to use “Copy from Work Items” and add the email previously written in a variable, it sometimes overwrites the request participants already present.

So I thought I would retrieve the accountID via web request, but it doesn't work.

E.g.:
rest/api/3/user/search?query={{issue.customfield_156.urlEncode}}

If I try to run the string directly in the browser, entering the email address works and displays it.
E.g.
rest/api/3/user/search?query=email@email.com

How can I do this? Any advice on how to handle this case?
Thank you

Hi @FrancoB!

You don’t need to make a web request for this. You can get the accountId from the custom field directly using:

{{customfield.accountId}}

And you’re right, if you set the Request participants field directly, it will be overwritten.
To avoid that, use the Advanced field update section instead, like this:

{
  "update": {
    "customfield_10038": [
      {
        "add": { "accountId": "{{responsavelLamina}}" }
      }
    ]
  }
}

Where:

• customfield_10038 → the ID of your Request participants field

• {{responsavelLamina}} → the accountId you extracted in the previous step

Hi @Deivid Araujo , 
could you kindly show me an example on how to use {{customfield.accountId}} to retrieve the id of a Customers user (portal access).
thanks
