I am trying to a create a product using the Printful api and python. I was able to create a product on there website (a basic) hoodie, and I wanted to try and create the same hoddie using python. Here is the documentation I am using: https://developers.printful.com/docs/#operation/createSyncProduct I keep getting this error which is very generalistic: { "code": 400, "result": "This API endpoint applies only to Printful stores based on the Manual Order / API platform. Find out more at Printful API docs.", "error": { "reason": "BadRequest", "message": "This API endpoint applies only to Printful stores based on the Manual Order / API platform. Find out more at Printful API docs." } } here is the code I am trying for testing: import requests import json my_key = "my_token" headers = { "Authorization" : "Bearer "+my_key } data = { "id": 302079884, "external_id": "8136758395169", "name": "Unisex Hoodie", # "variants": 6, "thumbnail_url": "https://cdn.shopify.com/s/files/1/0713/4275/2033/products/unisex-premium-hoodie-black-front-64079acdc1ff0_grande.jpg?v=1678219998", "is_ignored": False } data = json.dumps(data) products = requests.post("https://api.printful.com/store/products",headers=headers,data=data) print(json.dumps(products.json(),indent=4)) I am not sure how to test this code because the response is very generalistic. I was able to test my token to make sure it works by trying to get the product I made on the website: import requests import json my_key = "my_token" headers = { "Authorization" : "Bearer "+my_key } products = requests.get("https://api.printful.com/sync/products",headers=headers) print(json.dumps(products.json(),indent=4)) and I got the response: { "code": 200, "result": [ { "id": 302079884, "external_id": "8136758395169", "name": "Unisex Hoodie", "variants": 6, "synced": 6, "thumbnail_url": "https://cdn.shopify.com/s/files/1/0713/4275/2033/products/unisex-premium-hoodie-black-front-64079acdc1ff0_grande.jpg?v=1678219998", "is_ignored": false } ], "extra": [], "paging": { "total": 1, "offset": 0, "limit": 20 } } So I know I am hitting the api correctly. If anyone has any suggestions on how to create a basic product using the printful api, that would be awesome. EDIT: I also tried what @Driftr95 mentioned regarding wrapping the data around "sync_product" but that still didn't work. Here is the new data variable now: data = { "sync_product": { "name": "API product Bella", "thumbnail": "https://imagemagick.org/image/wizard.jpg" }, "sync_variants": [ { "retail_price": "21.00", "variant_id": 44666144522529, "files": [ { "url": "https://imagemagick.org/image/wizard.jpg" }, { "type": "back", "url": "https://imagemagick.org/image/wizard.jpg" } ] } ] } but I still get: { "code": 400, "result": "This API endpoint applies only to Printful stores based on the Manual Order / API platform. Find out more at Printful API docs.", "error": { "reason": "BadRequest", "message": "This API endpoint applies only to Printful stores based on the Manual Order / API platform. Find out more at Printful API docs." } } That response is so vague it is very hard to tell what is wrong with the post data I am trying to send. Continue reading...
