Title: Subscription Failure Error Last modified: August 3, 2021 --- # Subscription Failure Error * Resolved [toxoplasmaarts](https://wordpress.org/support/users/toxoplasmaarts/) * (@toxoplasmaarts) * [4 years, 10 months ago](https://wordpress.org/support/topic/subscription-failure-error/) * Hi, * I saw an old thread with this issue, but no resolution. We are experiencing this issue now with some regularity- receiving emails with this message: “SS_WC_MailChimp_Handler:: maybe_subscribe(): WooCommerce MailChimp subscription failed: Your merge fields were invalid. (ss-wc-mc-api-request-error)” * I got the error the first time a few weeks ago, so I double-checked our merge fields on our pop-up and embedded form against our contact list. I found one error and fixed and all was fine. Today, I had five emails come in consecutively with the error. I’ve triple-checked our merge fields, run tests with my own personal emails, and confirmed that our API key is active. The plugins and WordPress are up to date. Please advise. * WordPress 5.8 WooCommerce 5.5.2 WP WooCommerce Mailchimp 2.4.4 * Thank you! * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fsubscription-failure-error%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 7 replies - 1 through 7 (of 7 total) * Thread Starter [toxoplasmaarts](https://wordpress.org/support/users/toxoplasmaarts/) * (@toxoplasmaarts) * [4 years, 9 months ago](https://wordpress.org/support/topic/subscription-failure-error/#post-14798102) * Hi there, I just wanted to follow up on this– we’ve gotten two more of these.

This should provide more detail regarding which merge field is having an issue. * The most common error is an error with the ADDRESS merge field. Even if it is not marked required, if there is an error with the ADDRESS merge field, you will get back a “Please enter a complete address” error. * This means that the merge field “ADDRESS” is missing or incomplete. When there is an incomplete or invalid address on a subscriber, Mailchimp will not let you or any third-party app (i.e. our plugin) update any merge field until the invalid field has been fixed. Unfortunately, Mailchimp does allow some connected e-commerce platforms to sync subscribers even though they have invalid addresses. * Plugin Author [Saint Systems](https://wordpress.org/support/users/saintsystems/) * (@saintsystems) * [4 years, 8 months ago](https://wordpress.org/support/topic/subscription-failure-error/#post-14945349) * We have published another small update v2.4.7 to tell the Mailchimp API to skip merge field validation. * Please update and let us know if you encounter the error again. * Thread Starter [toxoplasmaarts](https://wordpress.org/support/users/toxoplasmaarts/) * (@toxoplasmaarts) * [4 years, 8 months ago](https://wordpress.org/support/topic/subscription-failure-error/#post-14959200) * Hi there! Thank you so much for the information. Actually, we got another error email today.
