How to get image embedded on issue description from REST API

[Lair Ortega Dehonor]

Hi,

I am using the jira rest api and when y query some issue i can get the description and if an imager were embedded in the description the API returns me something like this:

(
 [type] => mediaSingle
 [attrs] => stdClass Object
 (
  [layout] => center
 )

 [content] => Array
 (
  [0] => stdClass Object
   (
    [type] => media
    [attrs] => stdClass Object
     (
      [id] => 52fa9b66-4880-...-8840ae2ff490
      [type] => file
      [collection] => jira-918-field-description
      [width] => 200
      [height] => 183
     )
    )
  )
)

 How could i get the image attached there?

I have tried call the endpoint: GET /rest/api/3/attachment/{id}

But does not accept me the id I get this error: 

{"errorMessages":["El archivo adjunto con id '52fa9b66-...-8840ae2ff490' no existe"],"errors":{}}

In the issue response has the node attachment within it i can find the id corresponding with the attachments but I don't know hwo to link each attachment (image) to the enbedded images.

The attachment object looks like this:

[attachment] => Array
  (
    [0] => stdClass Object
      (
        [self] => https://api.atlassian.com/ex/jira/.../rest/api/3/attachment/....
        [id] => ....
        [filename] => 01.1.1 Login-touchID-activar.jpg
        [author] => stdClass Object
          (
            ...
          )

        [created] => 2019-05-24T10:50:23.914-0500
        [size] => 113023
        [mimeType] => image/jpeg
        [content] => https://....atlassian.net/secure/attachment/..../01.1.1+Login-touchID-activar.jpg
        [thumbnail] => https://....atlassian.net/secure/thumbnail/..../01.1.1+Login-touchID-activar.jpg
      )
      ....
  )

If I query the attachment id on the /rest/api/3/attachment/{id} endpoint i can get the image information and the file content but i can not link it with the embedded one in the issue description.

Is there any way to achive this?

Thanks.

I found a solution. For me it was related to using api/2 vs api/3. Using api/2 you can send a string that equivalent to what you put in in "edit" of description field text.
