ADSGRAM Creative formats & specifications
Technical requirements for current network creatives.
Bot and channel posts
The pilot uses a title, plain-text body, optional HTTPS image and one button. Title: 1–100 characters. Body: 1–700 characters. Button label: 1–32 characters. Internal name: 1–100 characters. Destinations and image links must use HTTPS and cannot embed credentials.
Publisher rendering
Display the Sponsored label clearly. Preserve the destination click URL provided by the API. Send title and body as plain text or escape them properly before applying Telegram HTML formatting. Do not treat supplied text as executable markup.
Media limits
Image URLs are stored rather than uploaded or transformed. Publishers must ensure their chosen image can be sent by Telegram. Video, task and rewarded formats are not accepted by this pilot API.
