I’m building an automation in Make where I generate images through an HTTP request to OpenAI’s new GPT-Image-1 model. The result I get from this API is an image in Base64 format.
What I want to do:
Take this Base64 image and create a Pin on Pinterest using the Pinterest module in Make.
The problem:
The Pinterest module always tells me that the image is “broken” or “corrupted”.
However, when I test the same Base64 string on an online Base64 to PNG converter, the image displays perfectly, so the data is valid.
What I’ve tried:
I also tried uploading the image to Imgur first, but in the Imgur module on Make, I don’t see any clear way to upload the Base64 directly.
When I use an image URL (from a hosted image), Pinterest works fine – so it seems the issue is with handling Base64 directly in the Pinterest module.
What I’m looking for:
A solution to either decode the Base64, host it temporarily as a public URL, and then use that for Pinterest.
OR an explanation why Pinterest rejects Base64 images even when the data is valid.
Any workaround to bridge this process smoothly from Base64 → public image URL → Pinterest.
Thanks in advance if anyone has experience with this or ideas on how to solve it!
How does this look like? How does your current scenario look like?
You have not yet provided sufficient information to demonstrate the problem that would allow us to reproduce the scenario and any error(s).
To allow others to assist you with your scenario, please provide the following:
1. Relevant Screenshots
Could you please share screenshots of your full scenario? Also include screenshots of any error messages, module settings (fields), relevant filter settings (conditions), and module output bundles. We need to see what you’re working with to give you the best advice.
You can upload images here using the Upload icon in the text editor:
We would appreciate it if you could upload screenshots here instead of linking to them outside of the forum. This allows us to zoom in on the image when clicked, and prevent tracking cookies from third-party websites.
2. Scenario Blueprint
Please export the scenario blueprint. Providing your scenario blueprint file will allow others to quickly recreate and see how you have set up the mappings in each module, and also allows us take screenshots or provide module exports of any solutions we have for you in return - this would greatly benefit you in implementing our suggestions as you can simply paste module exports back into your scenario editor!
To export your scenario blueprint, click the three dots at the bottom of the editor then choose ‘Export Blueprint’.
You can upload the file here by clicking on this button:
3. Output Bundles of Modules
Please provide the output bundles of each of the relevant modules by running the scenario (you can also get this without re-running your scenario from the History tab).
Click on the white speech bubbles on the top-right of each module and select “Download input/output bundles”.
Save each bundle contents in a plain text editor (without formatting) as a bundle.txt file.
You can upload the file here by clicking on this button:
B. Insert as Formatted Code Block
If you are unable to upload files on this forum, alternatively you can paste the formatted bundles.
These are the two ways to format text so that it won’t be modified by the forum:
Method 1: Type code block manually
Add three backticks ``` before and after the content/bundle, like this:
``` content goes here
```
Method 2. Highlight and click the format button in the editor
Providing the input/output bundles will allow others to replicate what is going on in the scenario, especially if there are complex data structures (nested arrays and collections) or if external services are involved, and help you with mapping the raw property names from collections.
Sharing these details will make it easier for others to assist you.
