If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.

In Bitrix24 e-Signature, you can configure data exchange with an external HR system. The integration helps automate HR document signing, reduce manual data entry, and lower the risk of errors.
With Bitrix24 e-Signature and HR system integration, you can:
- link Bitrix24 companies to companies in an HR system
- synchronize employees and map them to Bitrix24 users
- transfer HR system field values to fill e-Signature documents
- update synchronization jobs and track their status
The methods can only be executed in the context of authorization of the application. For most methods, the user must be an administrator.
Quick navigation: all methods
sign.b2e manages e-Signature documents: it sends a document for signing, retrieves a document, returns signing providers, and returns lists of signed documents.
humanresources.hcmlink supports e-Signature integration with an HR system. These methods create a link to a company in the HR system, upload employees, return mapped employees, and transfer field values that are later used to fill e-Signature documents.
Connecting a company. The application adds a company from an HR system using humanresources.hcmlink.company.add. The fields.crmCompanyId parameter passes the CRM company ID, and fields.fields passes HR system fields that will be available for filling e-Signature documents.
Synchronizing employees. When synchronization starts in the interface, the application receives the OnHumanResourcesHcmLinkEmployeeListRequested event with the job ID jobId, company code company, and request date. After that, the application transfers the employee list using humanresources.hcmlink.employee.set and completes the job using humanresources.hcmlink.job.update.
Mapping users. After Bitrix24 users are mapped to individuals from the HR system, the application receives the OnHumanResourcesHcmLinkEmployeeListMapped event. Use this event to request changed mappings with humanresources.hcmlink.employee.list. Pass the updatedAt parameter to retrieve only changes, not the entire employee list.
Requesting values for documents. When an e-Signature document is sent, Bitrix24 requests HR system field values using the OnHumanResourcesHcmLinkFieldValueRequested event. The event contains jobId, the company code, the employee list, and the field list. The application transfers values using humanresources.hcmlink.field.value.set, then updates the job using humanresources.hcmlink.job.update.
The exchange uses two employee identifiers from the HR system:
person— the individual code in the HR systememployee— the employee code in the HR system
One individual can be linked to multiple employees in one company, for example if the person has several positions. Bitrix24 maps a user to person, and requests field values for documents by employee.
Payroll and Vacation. For payslip and vacation balance pages, the application registers the HCMLINK_SALARY_VACATION embedding. The humanresources.hcmlink.company.user.list method returns companies where the current user is mapped to an individual from the HR system.
PIN and payroll data. PIN requests and payroll and vacation data requests use the OnHumanResourcesHcmLinkPinRequested and OnHumanResourcesHcmLinkSalaryVacationRequested events. Responses for these jobs are transferred using humanresources.hcmlink.field.value.set.
CRM company. The humanresources.hcmlink.company.add method links a company from an HR system to a CRM company through the fields.crmCompanyId parameter. You can get the company ID using crm.item.list with the entityTypeId = 4 parameter and the isMyCompany = Y filter. In the interface, these companies are located in CRM > More > Settings > My Company Details. This ID is used in e-Signature methods when a document is sent on behalf of a company.
Bitrix24 employee. The humanresources.hcmlink.employee.set method links an employee from an HR system to a Bitrix24 user through data[].userId. After mapping, e-Signature documents can be sent by employeeId or employeeCode in sign.b2e.document.send.
HR system fields. The list of available fields is transferred when a company is added or updated. The codes of these fields are used in value request events and in humanresources.hcmlink.field.value.set.
