Talend -- Rest API call

Question

I am currently building an ETL job in Talend Open Studio, that calls an API to get data, the API call is OAuth 2.0 Authorized with an access token which I have to get by passing some values that are Base 64 Encoded, I am struggling in the part of getting access token

Answer 1

As written in the linked docs

To obtain a token you needyourAPI Key, API Secret, Trustpilot username and password.

Then you call

Method: POST
https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken

With Headers:

Authorization: Basic [BASE64_ENCODED(API_KEY:API_SECRET)]
Content-Type: application/x-www-form-urlencoded

Noting that The KEY AND SECRET needs to be concatenated as follows KEY:SECRET and then base64 encoded

---

You should get your token and encoded valuesoutside of Talend(although, there probably is a base64 encoding processor).

Then you can use tHttpRequest to call other API endpoints listed in TrustPilot docs.
