I need a script that posts Offer Images to my Amazon Seller Central account through the Selling Partner API (SP-API). The images are already curated and meet my own standards, so there is no need to build in Amazon guideline validation—just get them up quickly and accurately. Please see the attached files for further details. I am looking for someone who is already familiar with the Amazon SP-API and who has already developed a working script for uploading offer images before. Note that what I am looking for is a script to upload OFFER images. Offer images are directly linked to an inventory SKU Number and are not the same as the generic product images that are shown on the Amazon product detail page. The chosen developer will be in communication with my primary software developer. His project notes are posted below and he has prepared a set of project files which are available in the project attachment. Developer Notes: "UploadBookImages.py is a sample Python script uploading images for the given SKU to its [Images] section of an Amazon Seller Central account (see screenshot '1. Images Section.jpeg'). The required task to solve is to develop a Python script (or C# console app) to upload images for the given SKU to its [Offer] section of an Amazon Seller Central Account (see screenshot '2. Offers Section.jpeg'). config.py contains a custom class defining UploadBookImages.py scripts context: SELLER_ID, REFRESH_TOKEN etc. All values are fake as they are Amazon Seller specific and should be kept in secret." Scope • Authenticate with SP-API using my LWA credentials and refresh token. • Call the Listings Images endpoints (or any newer image-upload operation Amazon releases) to attach an image to the correct ASIN-SKU offer. • Return the Amazon response so I can log image URL, status, and any error messages. • Map multiple images in one run is a plus, but single-image proof of concept is fine for hand-off. Deliverables 1. Source code (Python, Node.js, or another mainstream language—your choice) with clear setup instructions. 2. A short README describing required environment variables, how to invoke the upload, and expected output. 3. One successful test run on my sandbox or live account to confirm the image is visible on the offer page. Future flexibility to extend the same logic to Product, Variant, or Marketing images is appreciated, but today’s task is strictly Offer Images. Familiarity with AWS SigV4 signing and SP-API rate limits will help you breeze through the build.
