SendGrid announced they are sunsetting two of their API endpoints this month. In an email sent to their API consumers, Sendgrid stated that all API calls must now use a new base URL. They also directed developers to reference SendGrid’s API documentation or contact them through their attached email.
SendGrid announced its latest endpoint for its Web API: v3/mail/send. The endpoint rounds out the v3 release that began last year. With the new send endpoint, SendGrid has realized its goal of complete API management via API. All of the v2 functionality remains available with additional features.
