I am working on another plugin that offers the users the possibility to opt-in the client’s mailchimp. * I’d like to know if this can be done programatically by calling a function in your plugin. If so, where should I look? * Thank you. * [https://wordpress.org/plugins/yikes-inc-easy-mailchimp-extender/](https://wordpress.org/plugins/yikes-inc-easy-mailchimp-extender/) Viewing 7 replies - 1 through 7 (of 7 total) * Plugin Author [Evan Herman](https://wordpress.org/support/users/eherman24/) * (@eherman24) * [10 years, 5 months ago](https://wordpress.org/support/topic/programmatic-opti-in/#post-6821159) * Hi Acub, * How are you planning on having users optin? Via checkbox? There is no way to programatically opt-in a user using our plugin. My recommendation would be to directly integrate with the MailChimp API. That way you can write a small function to subscribe users with. * Our plugin expects some form data to be entered, which is the data that actually gets sent over to the MailChimp. If you need some pointers setting things up, I’d be glad to help out in any way I can. * Evan * Plugin Author [Evan Herman](https://wordpress.org/support/users/eherman24/) * (@eherman24) * [10 years, 5 months ago](https://wordpress.org/support/topic/programmatic-opti-in/#post-6821237) * I’m going to close out this issue.

Thank you for your replies. * Yes, in a more complex plugin, at the final step I ask users if they would like to sign-up for our newsletter. And with that information, if they said yes, I’d like to automatically sign them up, having their acceptance and email address. I’m not familiar with MC, I’m assuming that will trigger an email from MC so they can confirm their email address and their option (am I wrong?). * So, just to make sure: your plugin does not have an embedded function that can call the MC Api for me, I need to build a method for that myself, is that correct? I was hoping I could skip authenticating with MC, as I’m assuming your plugin already handles that. * I’m asking because I’ve never worked with MC before. I’ll read the API if I need to, but I won’t if there’s any way around it. 🙂 * Until we finish this conversation, I’ll mark it as [not a support question], so it doesn’t affect your support ratings. * While looking forward to your response I thank you for your time. * Plugin Contributor [Tracy Levesque](https://wordpress.org/support/users/liljimmi/) * (@liljimmi) * 🏳️‍🌈 YIKES, Inc.

But we have this add-on functionality for a few popular plugins like Contract Form 7, WooCommerce, etc. Where our plugin adds an opt-in checkbox to the end of a form. If the form is checked then it’s starts the double opt-in process with MailChimp (an email is sent to the user where they can confirm they indeed want to join the list). * I am thinking you could add this to your custom function as well with a hook. I’ll let Evan answer that part 🙂 * Thanks! -Tracy * Plugin Author [Evan Herman](https://wordpress.org/support/users/eherman24/) * (@eherman24) * [10 years, 5 months ago](https://wordpress.org/support/topic/programmatic-opti-in/#post-6821270) * Hi acub, * Unfortunately each of the bundled extensions (CF7, EDD, WooCommerce etc.) have a separate class with functions defined specifically for those plugins and have had extensive work done on them to be able to integrate with each of the plugins. * Feel free to have a look through any of our bundled integrations: [https://github.com/yikesinc/yikes-inc-easy-mailchimp-extender/tree/5dd3cd24c92b284b1b02ce795e972047c964576d/plugin_core/public/classes/checkbox-integrations](https://github.com/yikesinc/yikes-inc-easy-mailchimp-extender/tree/5dd3cd24c92b284b1b02ce795e972047c964576d/plugin_core/public/classes/checkbox-integrations) * You should be able to see how we handle each one. * If you can explain your plugin in extreme detail as to what you are after, I might be able to point you in the right direction. I’m just not sure what you’re trying to do as there are a number of ways you can attack the problem at hand. * Thanks, Evan * Thread Starter [acub](https://wordpress.org/support/users/acub/) * (@acub) * [10 years, 4 months ago](https://wordpress.org/support/topic/programmatic-opti-in/#post-6821281) * Thank you very much. I’ll try to create a reusable class for opt-in, just in case it might be useful to anyone in the future. * I really appreciate your help. * My plugin is quite specific, it’s for an English Language Learning Centre and they have this quiz on their website. At the end of the quiz, they ask for the email to send results and also they wanted a checkbox for newsletter signup. * If it’s checked, besides sending results to both quiz taker and teacher, I need to initiate the double opt-in process. That’s about it.
