Zalo OA graphic templates
Dress a Zalo Official Account end to end — the OA cover, an ad banner, a broadcast header and a promotion image — each refilled from your campaign of the week. For OA operators running announcements and offers to their followers, not designing one banner at a time.
39 more templates in this category, opening with the API at launch.
Demo renders are rate-limited and not for production use.
Every Zalo broadcast and offer wants its own banner, and they never stop coming.
A new promotion, a fresh article to push, an updated cover for the season — each one stalls waiting on a designer or goes out looking thrown-together. But a Zalo banner is structured: a headline, an offer, a code, a call to action. Lock each format once and render the whole OA — cover, ad, broadcast header and promo image — from your campaign data, so refreshing the account is a data edit, not a redesign.
What you're probably thinking.
“Which Zalo formats does this cover?”
The four an Official Account actually uses: the OA profile cover, an ad banner, a broadcast article header and a standalone promotion image — each its own template with fields sized for where it appears.
“How does a discount code or campaign name get onto the banner?”
The headline, offer line, coupon code and CTA are text fields you pass per render, so one promotion template carries a new code and deal on every send.
“Can I keep the OA looking consistent as campaigns change?”
Your logo and accent colour are brand-bound, so they pull from your Brand Profile on each send and an OA cover and a mid-year promo image stay one identity.
“What format do these export as?”
High-resolution PNG, ready to upload as a Zalo OA cover, attach to a broadcast, or run as an ad creative.
“Can I wire this into an automated broadcast?”
Yes — call the render endpoint from n8n, Zapier or your own script and drop the returned image into the broadcast the moment the copy is set.
Render your first one.
Same deterministic engine, your data — on-brand, identical every time. Your first batch is free, no card required.
