# CRM API overview

Connect your product to your customers’ CRM systems. Work with companies, contacts, opportunities, and sales activity through a shared API model.

## From CRM systems to your customer workflows

Customer systems → Apideck CRM API → Your product.
Customers authorize their system through Vault. The unified model gives your integration a consistent shape. Available operations and fields vary by connector.

## Understand the core resources

- [Companies](https://developers.apideck.com/apis/crm/reference/companies.md): Business accounts and organizations in the connected CRM.
- [Contacts](https://developers.apideck.com/apis/crm/reference/contacts.md): People and contact details associated with customer relationships.

## Get connected in three steps

1. [Check coverage](https://developers.apideck.com/apis/crm/coverage). Confirm the connector exposes the operations and fields your workflow needs.
2. [Authorize a connection](https://developers.apideck.com/guides/vault.md). Create a consumer for your customer and use Vault to connect their system.
3. [Make and verify a request](https://developers.apideck.com/get-started.md). Use your server-side credentials to read a supported resource, then inspect the response and request logs.

## Implementation considerations

- Decide which system owns each field and how to handle edits made on both sides.
- Map company and contact identifiers before creating related records to avoid duplicates.
- Check connector coverage and required fields before writing sales records or activities.

## Explore CRM connectors

[Browse the searchable connector catalog](https://developers.apideck.com/apis/crm) and follow each connector’s setup instructions. Status and resource coverage vary. Use the catalog for current connector entries rather than treating this overview as a coverage snapshot.
