How do I sign in / Unsubscribe ? 24 May 2021 10:00 Updated You just have to fill the registration form. To unsubscribe, sign in to your Testapic account with the email you used to sign up and click on “Unsubscribe”. Related articles I have completed a test, how do I get paid? I have no credit on my account even though I have performed tests I have registered a while ago but I have not received any tests. Is it normal ? When and how does Testapic contact me to execute tests ?
