@Santhosh, @juventinoromero
Solve the problem as follows:
headers: {
"Authorization": Basic QmpES1ladkpYbmtDSlo6,
"Content-Type": "application/json"
},
After many attempts I decided to get my API KEY and encode it in base64, done that I passed my key in base64 in authorization and it worked. Thank you for all the support and attention in the case.
