Instagram Graph API:

Content Publishing:
https://developers.facebook.com/docs/instagram-api/guides/content-publishing/
My code Javascript in Google App Script:
function InstagramPost() {
const id = '123456789';
const image = 'https://www.w3schools.com/images/w3schools_green.jpg';
const text = 'Hello%20World';
const access_token = 'TESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTESTTEST';
const container = 'https://graph.facebook.com/v11.0/' + id + '/media?image_url=' + image + '&caption=' + text + '&access_token=' + access_token;
const response = UrlFetchApp.fetch(container);
const creation = response.getContentText();
Logger.log(creation);
}
The return in my Logger of my container to Post via Instagram API request comes as follows:
{
"data": [
{
"id": "11111111111111111"
},
{
"id": "22222222222222222"
},
{
"id": "33333333333333333"
}
],
"paging": {
"cursors": {
"before": "QWOURQWNGEWRONHWENYWPETGNWQPGNPGNWEPGNWEPGNWEPNGWPENGPWEG",
"after": "WIWEPGNEPBNWE´GNÉ´BNWE´BNWÉBWNEB´WENBNWEBWEBEWBWE"
},
"next": "https://graph.facebook.com/v11.0/11111111111111111/media?access_token=PQWNFWPQINPWNBQPWNBQPWNBPQWNVQWPNVPQWVNPQWPVNQPWNVQPWVNQPWNVPQWNVQPWNVQPWVNQASASLGÇAJKSGLJAAÇSNAÇKNSVÇLKNASBÇANSBÇAS"
}
}
To make the final call for post image it is necessary to use an creation_id=:
const sendinstagram = 'https://graph.facebook.com/v11.0/' + id + '/media_publish?creation_id=' + creation + '&access_token=' + access_token;
UrlFetchApp.fetch(sendinstagram);
If the return from the container is several id in sequence, how do I know which one to define for the call?
Note: I can't loop to try every id because Instagram has a daily limit of 25 calls and posts, so if I did that I would end up with my calls just trying to post a single image.
I found the correct way to publish images:
var formData = {
'image_url': image,
'caption': text,
'access_token': access_token
};
var options = {
'method' : 'post',
'payload' : formData
};
const container = 'https://graph.facebook.com/v11.0/' + instagram_business_account + '/media';
const response = UrlFetchApp.fetch(container, options);
const creation = response.getContentText();
var data = JSON.parse(creation);
var creationId = data.id
var formDataPublish = {
'creation_id': creationId,
'access_token': access_token
};
var optionsPublish = {
'method' : 'post',
'payload' : formDataPublish
};
const sendinstagram = 'https://graph.facebook.com/v11.0/' + instagram_business_account + '/media_publish';
UrlFetchApp.fetch(sendinstagram, optionsPublish);
First, we create IG Container by hitting the endpoint.
POST https://graph.facebook.com/v11.0/{ig-user-id}/media?image_url={image-url}&caption={caption}&access_token={access-token}
Once you have the IG container ID then we again make a POST request to post the Image.
POST https://graph.facebook.com/v11.0/{ig-user-id}/media_publish?creation_id={creation-id}&access_token={access-token}
I think you have to include the version in container and sendinstagram which is v11.0 (latest as if now).
