Advertiser Terms
Additional contractual terms for business entities and sole proprietors that create, fund, purchase, or manage advertising through Posto. These Terms supplement the Terms of Service.
Effective 2026-10-02 · Version 2026-10-02 · Permanent version
1. Advertiser authority and responsibilities
Advertiser shall be responsible for its account, Authorized Users, agents, campaign instructions, advertised products and services, creatives, offers, claims, disclosures, and landing destinations. Advertiser shall complete requested business verification and possess ownership or documented legal authority to advertise each product, brand, creative, destination, and associated intellectual property.
An agency, reseller, or other intermediary shall maintain authority to act for each represented business, identify that business when reasonably requested, and ensure that its instructions and submissions comply with the Agreement. Acting through an intermediary does not excuse the contracting Customer's obligations or create authority that the represented business has not granted.
2. Advertising standards
Advertiser shall ensure that each advertisement and destination satisfies the following requirements throughout the campaign:
- Claims shall be truthful, current, adequately substantiated, and not misleading by statement, omission, presentation, or destination. Advertiser shall possess competent substantiation before making an objective claim and retain supporting records for the campaign and any reasonably relevant dispute or legal period.
- Advertisements and destinations shall comply with applicable advertising, consumer-protection, intellectual-property, platform, and industry requirements and Posto's applicable published standards. Advertiser shall supply required sponsorship, endorsement, affiliate, material-connection, subscription, and recurring-charge disclosures.
- Advertiser shall not promote illegal, infringing, deceptive, discriminatory, malicious, or unsafe content or products. A category restricted by Posto requires Posto's prior written approval, which does not authorize conduct prohibited by law.
- Prices, availability, geographic limits, eligibility conditions, recurring charges, cancellation and refund conditions, and other material limitations shall be accurate and readily available where needed to avoid deception. Advertiser shall promptly update or pause a campaign when its content becomes materially inaccurate.
3. Campaign instructions and auction delivery
The budgets, objectives, target metrics, dates, eligible products, bids, and constraints confirmed by Advertiser constitute its campaign instructions. Posto may use automated matching and campaign-assistance systems within the configured controls. Advertiser shall review suggested or generated content and authorize publication through the applicable workflow; connecting a catalog or importing an unpublished listing does not itself authorize advertising that listing.
Auction delivery, placement, fill, and results are not guaranteed. Unless an Order expressly provides otherwise, eligible impressions are priced under the applicable disclosed auction rules, subject to bid, relevance, Publisher floor, pacing, available budget, and safety or eligibility controls. A target metric is an optimization instruction rather than a warranty of a particular outcome.
4. Funding, spend, and credits
Advertiser shall maintain sufficient available funds and pay valid advertising spend, applicable taxes, and chargeback or processor fees disclosed at checkout or in an Order. A campaign budget caps authorized spend under the campaign rules and does not require Posto to deliver enough advertising to spend that amount.
Unused campaign reservations return to the Posto account balance under the applicable product rules; they are not automatically refunded to the original payment method. Payments and unused funds are subject to the general nonrefundability rule in Section 8 of the Terms of Service, including its exceptions for legally required refunds, correction and refund of duplicate or erroneous overpayments, and a refund for a paid Service Posto cannot provide unless Advertiser agrees to an appropriate service credit.
Promotional credits are available only under the offer's disclosed eligibility and expiry conditions, have no cash value, and are not transferable or redeemable for cash. Posto may withhold or reverse a credit for a payment reversal, dispute, abuse, duplicate account, or other disclosed ineligibility. Simulation and test balances do not represent money.
5. Measurement and conversion accuracy
Posto measures delivery using authenticated application events and its tracking controls. Advertiser may enable the browser Pixel for supported website events and use the Conversion API, supported store integration, or trusted mobile measurement partner for eligible server-confirmed outcomes. The Advertiser Event and Conversion API Data Notice governs the relevant submissions and their handling.
Advertiser shall report genuine actions, use the same stable deduplication identifier for the same action across channels and retries, preserve the Posto click identifier required for final-event attribution, and provide accurate event time, transaction information, value, and currency. Advertiser shall correct or reverse outcomes that are cancelled, refunded, or invalid under the applicable event rules. Posto may reject, deduplicate, reverse, or exclude unsupported, unverifiable, fraudulent, or otherwise invalid events and may reconcile reporting and related charges accordingly.
6. Data use, privacy, and catalog confidentiality
Advertiser may use Posto reports to evaluate and operate its own campaigns. Advertiser shall not attempt to identify End Users, combine reports into sensitive profiles, target prohibited categories, or use Posto-provided data to train a model unrelated to campaign operation without Posto's written permission and any independently required legal authority. Posto does not disclose submitted ad-request transcripts to Advertisers through campaign reporting.
Advertiser shall provide accurate notices and obtain the lawful basis and specific permissions required for its measurement, browser storage, connected-store access, and disclosures to Posto. The standalone Pixel requires Advertiser's implementation of applicable consent and opt-out controls. Acceptance of the Agreement does not supply an End User's consent.
Customer Content remains subject to the ownership, limited license, and confidentiality provisions of the Terms of Service. Draft, archived, and unlisted catalog materials are not public merely because an integration imports them. Advertiser shall configure publication and data access within its authority and shall not include prohibited sensitive information in events, URLs, or submitted content.
7. Review, enforcement, and reconsideration
Posto may conduct automated checks and manual review before or after delivery and may request identity, agency authority, ownership, claim-substantiation, licensing, supply-chain, or destination records. Posto may reject, restrict, pause, preserve relevant evidence concerning, or remove content or campaigns to address applicable law, published standards, security, fraud, or credible account risk. Review or approval does not transfer Advertiser's responsibility for its advertising to Posto.
Advertiser may seek reconsideration through the support channel or legal@postoconnect.com by identifying the campaign and supplying relevant evidence. Posto shall provide a reason when legally and operationally practicable, subject to protection of investigations, security controls, and third-party information. Restoration does not validate previously invalid activity or eliminate accrued obligations.
8. Advertiser indemnity
Subject to Sections 13 and 14 of the Terms of Service, Advertiser shall defend and indemnify Posto and participating Developers against third-party claims and resulting covered losses to the extent arising from Advertiser's advertisements, products, destinations, offers, instructions, data, measurement events, regulatory noncompliance, or breach of these Advertiser Terms. The defense procedure, exclusions, aggregate liability limit, and prohibition on duplicate recovery in the Terms of Service apply. This provision does not impose liability for an indemnified party's own breach or unlawful conduct beyond what the Agreement and applicable law permit.
