Error trying to use an uploaded image in Linkedin - linkedin-api

Question

I'm trying to use the Linkedin API to share a post with an image. I've followed all the steps in the documentation:
https://learn.microsoft.com/es-es/linkedin/consumer/integrations/self-serve/share-on-linkedin?context=linkedin/consumer/context#share-media
First, I register the upload with a POST to https://api.linkedin.com/v2/assets?action=registerUpload and this body:
{
"registerUploadRequest": {
"recipes": [
"urn:li:digitalmediaRecipe:feedshare-image"
],
"owner": "urn:li:person:{{owner_ID}}",
"serviceRelationships": [
{
"relationshipType": "OWNER",
"identifier": "urn:li:userGeneratedContent"
}
]
}
}
I get this response:
{
"value": {
"uploadMechanism": {
"com.linkedin.digitalmedia.uploading.MediaUploadHttpRequest": {
"uploadUrl": "https://api.linkedin.com/mediaUpload/C4E22AQF6AS1WhrD1lw/feedshare-uploadedImage/0?ca=vector_feedshare&cn=uploads&m=AQKLg3lSJnswAgAAAXSgLwWp6iAPzjh6E_5XQh8QuP1Aucf_j9bgW3m5vQ&app=74851466&sync=0&v=beta&ut=2h9vtCSeuP0ps1",
"headers": {
"media-type-family": "STILLIMAGE"
}
}
},
"asset": "urn:li:digitalmediaAsset:C4E22AQF6AS1WhrD1lw",
"mediaArtifact": "urn:li:digitalmediaMediaArtifact:(urn:li:digitalmediaAsset:C4E22AQF6AS1WhrD1lw,urn:li:digitalmediaMediaArtifactClass:feedshare-uploadedImage)"
}
}
Then I use the uploadURL to make another post with the image as body, and get a 201 Created response.
I've checked the upload with a GET https://api.linkedin.com/v2/assets/C4E22AQF6AS1WhrD1lw and it has been uploaded correctly:
{
"recipes": [
{
"recipe": "urn:li:digitalmediaRecipe:feedshare-image",
"status": "AVAILABLE"
}
],
"serviceRelationships": [
{
"relationshipType": "OWNER",
"identifier": "urn:li:userGeneratedContent"
}
],
"mediaTypeFamily": "STILLIMAGE",
"created": 1600415270252,
"id": "C4E22AQF6AS1WhrD1lw",
"lastModified": 1600415345915,
"status": "ALLOWED"
}
When I try to share a post referencing this image I get this error:
{"message":"com.linkedin.restli.server.RestLiServiceException [HTTP Status:401]: com.linkedin.content.common.ResponseException: Writers of type person are not authorized to modify UserGeneratedContent.","status":401}
I'm sending a POST to this URL https://api.linkedin.com/v2/ugcPosts with this body:
{
"author": "urn:li:person:{{person_id}}",
"lifecycleState": "PUBLISHED",
"specificContent": {
"com.linkedin.ugc.ShareContent": {
"shareCommentary": {
"text": "Feeling inspired after meeting so many talented individuals at this year's conference. #talentconnect"
},
"shareMediaCategory": "IMAGE",
"media": [
{
"status": "READY",
"description": {
"text": ""
},
"media": "urn:li:digitalmediaAsset:C4E22AQF6AS1WhrD1lw",
"title": {
"text": ""
}
}
]
}
},
"visibility": {
"com.linkedin.ugc.MemberNetworkVisibility": "PUBLIC"
}
}
I can share an only text post without trouble, look at my person ID, even like a post, but I'm stuck with this.
Can anyone tell me what am I doing wrong?

Answer 1

Solved. I had an error in the person_id variable, so I was trying to create a post with the wrong id.
