Connector
A connector is a pre-built integration component that links two software applications, allowing them to share data automatically without requiring custom API development for each individual connection. Modern marketing technology stacks typically involve multiple platforms: a CRM, an email marketing tool, a web analytics platform, a data enrichment service, and advertising platforms. Connectors are what tie these systems together, enabling data to flow between them in real time or on a schedule.
Connectors are offered through several channels: native integrations built directly into a platform, integration middleware platforms like Zapier or Make that offer connectors between hundreds of tools, and marketplace ecosystems where third-party developers publish connectors for popular combinations. The quality of a connector varies: some are bidirectional, real-time, and field-mapping configurable; others are one-directional, scheduled, and limited in what data they transfer. For core, high-volume integrations like CRM to email platform, a native or direct integration is usually preferred.
For B2B marketing operations teams, connectors are the infrastructure of the integrated marketing stack. A well-connected stack means that a new lead created in your email platform automatically appears in your CRM, that a contact’s lifecycle stage change in the CRM automatically triggers a new email sequence, and that ad audience lists are automatically updated as contacts move through the funnel. The quality and reliability of these connections directly affects the quality of your automation and the accuracy of your personalisation.
What is the difference between a connector and an API?
An API is the technical interface that allows two applications to communicate programmatically. A connector is a pre-built implementation of that API connection, packaged to work with a specific pair of applications without requiring custom code. Using an API to build an integration requires development work; using a connector means the integration path is already built and can often be configured through a visual interface by a non-developer. Connectors use APIs under the hood; they are the accessible layer on top of raw API capabilities.
What is a native integration versus a third-party connector?
A native integration is built and maintained by one or both of the platforms being connected, and typically offers deeper functionality, more reliable data syncing, and tighter feature compatibility. A third-party connector, provided by a middleware platform like Zapier or Make, works with many tools but may be more limited in the data fields it can access, the sync frequency it supports, and the complexity of logic it can handle. For core, high-data-volume integrations, a native or direct API integration is usually preferred.
What connectors does a B2B marketing team typically need?
The most valuable connectors in a typical B2B marketing technology stack are: CRM to email marketing platform (to sync contact and lifecycle data bidirectionally), email platform to web analytics (to track post-click behaviour from email), CRM to advertising platforms (to build custom audiences from CRM data), and data enrichment services to CRM (to keep contact data current and complete). The specific connectors needed depend on the tools in your stack and the data flows required to support your automation and personalisation goals.
