Contacts and replies
Avito contact identities useavito_user_id in the form <accountId>:<buyerId>. Both parts contain 1–128 letters, digits, underscores, or hyphens. Preserve the account prefix: the same buyer identifier in another account is a different identity.
Employees can reply to an existing Avito chat, including through Embed with showSendInput. Starting a new conversation from a contact identity is unavailable. Text is limited to 1000 characters. One JPEG/PNG photo of up to 10 MiB can be sent without a caption; document sending is unavailable. Storage settings can lower the file limit.
Listing context
Messages in Public API ticket history and incoming-message webhooks can include optionalcontext:
type and id are required when context is present. title, price, and the HTTPS url are optional. Price is display text, not a numeric amount. Different messages in one chat can refer to different listings. Context is separate from ticket attribution; do not assume it is available for every historical message.
