MCA & ROC Filing | MCA21 Portal Integration

MCA21 submission inside the platform. SRN tracking that does not need a separate dashboard.

Direct MCA21 API submission for the forms where the API is live. DSC-signed PDF generation for forms still on the legacy upload. SRN, payment challan and acknowledgement capture happen on the same record. Rejections come back with the reason and the corrective action.

MCA21 Portal Integration FAQ

What buyers ask.

Which MCA21 forms are submitted via API and which are legacy uploads?

The MCA21 V3 portal supports API submission for an expanding list including AOC-4, MGT-7 and many DIN-related forms. Forms not yet on V3 generate as DSC-signed PDFs for legacy upload, with SRN captured back. The platform tracks which forms are on which path so the user does not need to.

Multiple DSCs are needed (director plus CS plus CA). Is that handled?

Yes. The platform supports multi-DSC sign-off on a single form. Each signatory signs with their own DSC; the form record stores the certificate details, the role and the signing timestamp for each. The form submits only after all required signatures are present.

How are payment challans handled?

MCA21 fees are computed per form per entity. The platform generates the payment challan, captures the payment reference and attaches it to the form before submission. Payment is made through the MCA21 payment gateway in the same flow.

What if MCA21 is down?

API failures are logged with the response code. The platform retries automatically per the MCA21 retry policy. If the portal is in scheduled maintenance, the queue holds the submission and submits when the portal returns. Manual override is available where needed.
