Why isn't my ERP software integrating with Shopify API correctly?

[stevenstelljes]

Dear All,

We are integrating our ERP software with Shopify website. Whatever the Products and Orders are there in Shopify website, we are planning to sync to our ERP software. For that, we enabled private App in Shopify website. Then we tested through postman. It is working fine. Then we have copied auto generated Java Code from Postman and executed in our software. Then we are getting following error message. Could anyone help me on this "why integration is working through postman and same not working in our java code".

{"errors":"[API] Invalid API key or access token (unrecognized login or wrong password)"}

Hey @stevenstelljes, just curious, what ERP are you looking to integrate? And what platform or infrastructure are you using to host your java code?
