This situation involves the Speakatoo API performing correctly when tested in POSTMAN, but facing challenges when integrated into a larger system. Troubleshooting and resolution are needed to address these integration issues and ensure the API operates seamlessly within the intended environment.
Thank you for your post.
I am not aware of the Speakatoo API and it is not something we would support here. Do you have issues with the Crossref APIs? What issues are you having with the API? If it is working fine through POSTMAN then I suspect the issue is with the integration rather than the API but I will investigate further once I have more information.
