Duplicate collections when creating via Shopify API.

[Chrisabo]

Hi,

I'm creating collections via the rest-api and they appear twice.

I post to the URL:

....myshopify.com/admin/api/2023-04/custom_collections.json

I have the following headers:

content-type: application/json
X-Shopify-Access-Token: xxxxxxxxxx
Cache-Control: no-cache

This is the content:

{"custom_collection":{ "title":"Testcollection"}}

After sending the request to the rest-api the collection is added twice. Each has an unique ID.

What can cause this problem? I'm sending the request only once.

Any suggestions?

Best regards,
Chris Andries.
