Reddit Ads compatibility

This page compares the Reddit Ads capabilities represented in the Apostra adapter with what Apostra currently makes available to buyers. It answers a practical question: what can I do through Apostra today, and what would still require another path?

Last reviewed 2026-08-18. This is Apostra’s description of its own adapter, based on the implementation and the linked provider documentation. Reddit Ads has not reviewed or endorsed this page. Availability can still vary by account permissions, market, and provider access.

How to read availability

🟢 Available — Offered through Apostra now, subject to your ad account’s permissions and eligibility with the provider.
🟡 Partial — Some of the workflow is available; the Comments column explains the boundary.
🔵 Testing — Apostra is validating the workflow before offering it broadly.
⚪ Planned — Not offered through Apostra yet. The provider may still support it directly; Comments explains why and links a roadmap reference.

Roadmap

The adapter roadmap is tracked in AI-1943 (a plain-text reference — Apostra’s internal issue tracker is not public). This roadmap tracks Reddit adapter product completeness, sandbox readiness, and live readiness. Every row that is not currently available shows that reference or a more specific one in its References column, so customers and partners can quote a stable identifier when asking about a capability.

Connection, accounts, and identity

Reddit Ads connects to Apostra through an OAuth grant. Connecting a Business account gives Apostra access to each Ad account it can reach — you then map each one to your advertisers. The mapped account decides which Reddit Ads tenant a buy runs on: a media buy for an unmapped advertiser fails closed with account_mapping_required rather than silently using another account. Connection, account-discovery, and revocation behavior is the same across ad platforms — see Platform accounts and advertiser mapping for the full model and the Reddit Ads section of the connecting guide for Reddit Ads-specific permissions.

Apostra concept	Reddit Ads concept	What it represents
Account (`account`)	provider advertising account	OAuth resolves the selected Ad account through its owning Business; that exact account is the execution boundary.
Media Buy (`media_buy`)	campaign	Media Buy maps to campaign.
Package (`package`)	ad group	Budget, targeting, optimization, and flight bindings.
Creative Assignment (`creative_assignment`)	promoted post or creative	Creative materialization or assignment must use an authorized business profile; published-post reuse additionally requires exact source-community ownership and eligibility plus provider readback.

Reporting

Apostra reports Reddit Ads delivery day by day (there is no hourly delivery breakdown), aggregated nightly from adapter-reported delivery, in the advertiser’s home currency using the booked or historical exchange rate — any cross-currency rollup is always labeled an estimate and is never used for billing. See Reporting overview for the full model. Apostra does not currently publish an attribution-finality window for Reddit Ads; the table below lists every metric the adapter surfaces today.

Webhooks and async lifecycle

Reddit Ads does not push status, delivery, or reporting events into Apostra — every campaign product declares supports_webhooks: false.

Status. Apostra’s status-callback poller checks pending Reddit Ads creative status every 5 minutes (backing off to hourly as a status goes unchanged) and fires a one-shot AdCP task-completion webhook — the pushNotificationConfig a buyer can register on some async operations — once a creative reaches a terminal status. That is Apostra notifying the buyer’s own system, not Reddit Ads notifying Apostra. Media-buy status is not polled this way for any adapter today.
Delivery. Apostra has not yet made on-demand delivery fetching generally available for Reddit Ads — see Get Media Buy Delivery in “What the adapter can do” above. The /reporting/metrics endpoints never call the adapter either way — they read from a separately-populated store (see Reporting below), so a reporting request does not itself refresh provider delivery.

This is separate from Apostra’s own buyer webhook subscriptions — an unrelated account-level event feed (currently discovery.revision only), documented in Buyer webhooks.

Market and account availability

Apostra does not promise that every feature is enabled for every account or market. Availability is checked against your selected ad account rather than a global market list on this page.

Important limitations

Apostra implementation/testing. This page is not yet a confirmed complete catalog of every Reddit Ads creation path.
Apostra implementation/testing. The listed campaign products exist in the current adapter code but are still being certified before general availability.
Apostra implementation/testing. Dynamic Product Ads prospecting and retargeting are unavailable until Apostra implements the complete provider catalog, product-set, Pixel-event, shopping creative, placement, and readback workflow.
Apostra implementation/testing. Current conversion-intent, app, and community-intent products optimize for clicks, not Pixel conversions, purchases, app installs, or community engagement.
Apostra implementation/testing. Provider-rendered previews, separately selectable Reddit placements, provider push webhooks, and generally available published-post reuse are not currently offered.
