Boost credit limit
Upload a financial statement PDF to attempt a credit-limit increase.
POST
Boost credit limit
Submits a PDF statement (mobile money or bank) to the Manka AI engine.
If the statement is valid, recent, and yields a higher limit than the
customer’s current one, the customer’s pre-approved limit is increased
on the spot. All three outcomes — increased, unchanged, cooldown — return
The limit was raised from 30,000 to 55,000 TZS. The customer gets an
SMS confirming the new limit.
Statement passed validation but the Manka-derived limit didn’t exceed
the existing one. No database update. Customer is notified by SMS.
The customer was already boosted within the last 45 days. The
statement is not reprocessed; the existing limit is echoed back.
200 OK with the same response shape; branch on boostStatus and the
limit fields.
The upstream always sends an SMS to the customer’s mobile number
when this endpoint is called, including on validation failures. Treat
every successful call as an outbound communication event.
