Configuration reference

Number format

Zenziva accepts local (08123456789) or international (628123456789 without +) formats. Normalize to one format in your code — mixing causes confusion in delivery logs.

Regular vs Masking

Regular — cheapest. Recipient sees a random short code as the sender.
Masking — your brand name as the sender (e.g. BCA, Tokopedia). Better UX but more expensive and requires sender-name registration with Zenziva.

Troubleshooting

status: 2 (fail) — bad credentials or insufficient balance.
Message delivered status stuck at pending — carrier-side delay. Indonesian operators have intermittent slowness; don't retry too aggressively.
Masking sender rejected by carrier — Telkomsel/XL/Indosat each have their own sender-registration process, handled on Zenziva's side. If a sender works for some users and fails for others, it's probably not registered with the failing user's carrier.
