Procore API
Programmatic access to the data inside a Procore account.
Quick Answer
The Procore API is Procore's published REST interface that lets approved applications read and write data in Procore, such as projects, RFIs, submittals, drawings, and budget records. Access uses OAuth 2.0, and developers can also subscribe to webhooks, so outside tools stay in step with Procore without manual exports.
The Full Picture
Procore is a widely used construction management platform, and its developer program publishes a REST API so other software can work with the data stored there. Documentation, authentication guides, and a sandbox environment are provided through Procore's developer portal, which is the authoritative reference for endpoints and current behavior.
Access follows the OAuth 2.0 model. An application is registered with Procore, and either a user authorizes it to act on their behalf or, for server-to-server integrations, it authenticates as a service account under the platform's supported flows. What the app can see or change is then governed by the permissions of that user or account inside Procore.
Typical uses include syncing project and cost data with an ERP or accounting system, pulling RFI or submittal logs into reporting tools, and pushing records created elsewhere into Procore. Procore also supports webhooks so an integration can react when a resource is created or updated rather than polling repeatedly.
Because the API is vendor-controlled, endpoints, rate limits, and terms can change. Teams that depend on it should read the current documentation, build error handling and retries, and decide which system is authoritative for each data type. Many needs can be met by pre-built integrations in Procore's marketplace without custom development.
Real Examples
Common Misconceptions
People assume: The Procore API gives access to every feature in the Procore app.
Actually: The API covers the resources and actions Procore chooses to publish. Some features have limited or no API coverage, and access depends on the permissions of the authorizing user or account.
People assume: Anyone can connect to a company's Procore data with the API.
Actually: An app must be registered and authorized through OAuth, and it is limited by the account's permissions. The company's Procore administrators control what is shared.
Frequently Asked Questions
Is the Procore API free to use?
Procore provides developer documentation and sandbox access through its developer program, but terms, access, and any associated costs are set by Procore. Check the current developer portal and your agreement for specifics.
What authentication does the Procore API use?
It uses OAuth 2.0. Apps are registered with Procore and obtain access tokens either through a user authorization flow or a supported server-to-server flow.
Does Procore support webhooks?
Yes. Procore offers webhooks so an external system can be notified when supported resources are created, updated, or deleted, which avoids repeatedly polling the API.
Do I need to code to integrate with Procore?
Not always. Many common integrations are available as pre-built connectors in Procore's marketplace. Custom code is mainly needed for workflows those connectors do not cover.
How do I test an integration safely?
Use a sandbox or test environment rather than a live project, so you can verify field mapping and error handling before touching production data.
