Q&A

  • Why does call return a 404?

    Probably you misspelled the method. Please check the API documentation and keep in mind the methods are case sensitive.

  • Why does call return a 500?

    Maybe there's a problem with the ssl chain of trust. Either install Mozilla::CA or set (one of) the following environment variables PERL_LWP_SSL_CA_FILE, HTTPS_CA_FILE, PERL_LWP_SSL_CA_PATH, HTTPS_CA_DIR. See LWP::UserAgent for details.
