Hi @Larmier_Anthony, welcome to the community 
I am sorry to hear you’re having trouble here. On first sight it looks like in your expression you are using JSON.stringify(), which returns a string:

Could you try returning a JSON object instead of a string in your expression, for example by using an expression like {{ $json }}?
You can visualize the difference by temporarily sending your request to webhook.site instead of your API.
With JSON.stringify:

I attach a screenshot
Looking better, it was missing the [] after the data! Thank you very much for your help!
Nice, glad to hear this helped! Thanks so much for confirming and for sharing your solution
