Contribution Weeks

Credits: 3 per resolved request — charged when the result resolves; the ACCEPTED acknowledgement and Contribution Weeks Result are free.

Retrieves a worker’s official IMSS Certificate of Contributed Weeks (Constancia de Semanas Cotizadas) from their CURP: the official PDF issued by IMSS (with folio and digital seal), the full employment history parsed into JSON, and signals derived from that history (tenure, stability, salary evolution).

Immediate response: ACCEPTED with the transactionId, or INVALID_REQUEST if the request is not valid.

Result: delivered to your webhook. If your webhook could not receive it, you can fetch it for 24 hours with Contribution Weeks Result. Every result type, with its example, and how to read data, are in the Webhooks guide.

webhook

object

required

Where the result of an asynchronous request is delivered (HTTP POST with a JSON body).

Show child attributes

Response

Immediate response (Strict Envelope Pattern). The result is delivered to your webhook.

status

enum<string>

required

High-level outcome. OK means the request was successfully processed (regardless of business result). ERROR means the request was rejected or could not be processed.

Available options:

OK,

ERROR

type

string

required

Stable result type code. Includes generic codes (SUCCESS, INVALID_REQUEST, UNAUTHORIZED, SERVICE_UNAVAILABLE, INTERNAL_ERROR, RATE_LIMIT_EXCEEDED) plus endpoint-specific result codes — see this endpoint's response examples.

message

string

required

Human-readable summary of the result. Always in English (per Language Conventions in the API overview).

transactionId

string<uuid>

required

Unique identifier of this request, generated by the API Gateway. Propagated end-to-end for traceability.

processedAt

string<date-time>

required

ISO 8601 datetime with Mexico City offset (-06:00). Always set by the API Gateway when the response leaves the system.

billable

boolean

required

Whether this request will be charged against the client's plan. Typically true for successful business results and false for validation errors or system errors that prevented processing.

data

object | null

Response payload. null on error responses. Shape depends on the endpoint — see each operation's response schema.

errors

object[]

Per-field error details. Present only on INVALID_REQUEST responses.
