Definition of API
An API (Application Programming Interface) is a set of rules that lets different software talk to each other. For newsletters, APIs let your email platform connect with other tools like your website, payment processor, or content system without manual work. This enables automatic data transfer and actions between these systems.
Why you should care
APIs help you automate subscriber management, content creation, and data analysis. For example, when someone signs up for your 5-day email course through a landing page on your WordPress site, an API connection automatically adds them to your ESP and triggers the course sequence without any manual work from you.
The main obstacle is the technical knowledge barrier. Many creators know APIs could help but struggle with implementation or even knowing which connections would benefit their workflow most.
For your 5-day email course example, a properly configured API connection directly impacts your bottom line.
The automated welcome and course emails are trigger-based. Data suggests that these event-based messages drive higher engagement than regular broadcasts.

* Need to pass email, first name, and set proper UTM parameters
* Want to ensure subscribers are properly tagged for this specific funnel
</context>
<output>
Please provide:
* A step-by-step technical implementation plan
* Required API parameters and their values
* WordPress form configuration recommendations
* Pipedream workflow structure
* Testing methodology to verify the integration works
* Troubleshooting guidance for common issues
</output>
<example>
Sample API request structure:
{
"email": "{form_submission.email}",
"send_welcome_email": true,
"utm_source": "tokblocked_course",

{
"name": "First Name",
"value": "{form_submission.first_name}"
}
]
}
</example>
