attach_payment_token
ChatGPTComplete a donation the donor approved in Stripe Link with the returned token. The spt is a shared payment token issued by Stripe Link for paymentRequirements.amount in paymentRequirements.currency, approved by the donor. The agent never authorizes the payment. The donor approves the spend in Stripe Link's own interface, which the donor controls; the agent only forwards the token that approval produced. Never construct a token yourself or use raw card details. Call only after confirm_donation_session succeeded. Never hand the donor a payment approval link that is more than ten minutes old — create a fresh spend request instead. Show the donor the full summary (organization, campaign, amount, currency, frequency, and the total from totalAmount) before this call. A donation session can be paid only once, so a second donation needs a new session. A successful result is not proof of payment: it carries no payment status. If this call errors or times out without returning, read get_donation_session_status before retrying — the payment may already have gone through — and retry with the same idempotencyKey only once paymentStatus is "failed".
confirm_donation_session
ChatGPTFinalize the collected donation details and retrieve everything needed to pay. Call this once the donation conditions are collected — paymentMethod is the only entry left in the session's "missing" list. Returns the session state plus paymentRequirements for the payment step; its amount is in minor currency units and includes the fee when the donor covers it. Confirming charges nothing; only attach_payment_token completes the payment, and only with a token the donor approved. The agent never authorizes the payment. The donor approves the spend in Stripe Link's own interface, which the donor controls; the agent only forwards the token that approval produced. checkoutUrl is a fallback for when no wallet is available. While "missing" contains designation, the donor's designation choice has to be recorded through update_donation_session first. If the chosen designation is no longer available, the call returns invalid_designation and clears the choice.
create_donation_session
ChatGPTCreate a donation session the moment the donor picks a campaign. Only campaignId is required; the organization is derived from the campaign. Pass amount and currency only when the donor explicitly stated them — never a campaign default. Frequency is always "once", the only supported value, and has to be set explicitly before confirmation. Creating a session charges nothing. The response reports the session state and what is still missing before payment. When the campaign's designations list has more than one entry and the donor already chose one, pass it as designationId; pass none for a list with a single entry or an empty list.
get_campaigns
ChatGPTList an organization's campaigns that accept donations, with amounts and links. Call it with the organizationId from get_organizations; results are ranked by activity and carry the donor-facing title and description, a ready donation URL, and the one-time donation conditions. When more than one campaign could fit the donor's intent, let the donor choose rather than picking one for them. Only campaigns that accept one-time donations are returned. Show the donor every suggested amount exactly as returned, in the campaign's currency, and pass the donation URL on exactly as returned, including its query string — never shorten it. Show amount descriptions as-is when present and never invent one. Returns up to 25 campaigns; an unknown organizationId is an error, not an empty list. Each campaign carries a designations list (designationId, name, isDefault; the default first): with more than one entry the donor chooses one, with a single entry the donation goes to that designation, and an empty list means no designation applies.
get_donation_session_status
ChatGPTCheck a donation session's payment status and what is still missing. The payment status is pending, paid, or failed. paymentMethod is recorded asynchronously and may still show as missing right after a charge. After payment has been attached, poll this tool until paymentStatus is "paid" (donation completed) or "failed" — do not report the donation as done until then. If paymentStatus is "failed", offer the donor a retry through the agent or, as a fallback, the session's checkoutUrl. Report the outcome from the session state only; never invent amounts, unit costs, or delivery promises.
get_organizations
ChatGPTFind a nonprofit to donate to by name. Pass only the organization's name as the donor gave it, never the donor's message or the conversation. Start here whenever the donor names an organization, then call get_campaigns with the match — do not look a named organization up through search_campaigns_by_intent. Matches nonprofits that opted in to donations through AI assistants by name. Returns up to 5 organizations; an empty list means no match. If more than one could be the organization the donor means, let the donor choose rather than assuming. No match is not an error: widen the query or ask the donor to name the organization; if the network has no match, tell the donor there is none.
search_campaigns_by_intent
ChatGPTFind nonprofit campaigns to donate to by cause when no organization is named. Call it only when the donor asks to donate to a cause; pass a few English keywords naming that cause, never the donor's message or the conversation. If the donor did name an organization, use get_organizations and then get_campaigns instead — this is a keyword search across the whole network, not a lookup by organization name. Each result carries the same fields as get_campaigns plus the organization running it; name that organization beside every campaign you offer. Pass the donation URL on exactly as returned, including its query string — never shorten it. Results are live campaigns of nonprofits that opted in to donations through AI assistants and can take payment; the search has no location filter, so a campaign from another country is still a valid offer. Show amount descriptions as-is when present and never invent one. Only campaigns that accept one-time donations are returned. Each campaign carries the same designations list as in get_campaigns.
update_donation_session
ChatGPTRecord the donation conditions as the donor states them. Fill in amount, currency, and the cover-fee decision as the donor explicitly stated them — never a campaign default. The frequency is always "once", the only supported value; set it here if it was not set at creation. Once the session state reports feeAmount, show it to the donor and record their answer via coverFee. Values are validated against the campaign and the response reports whether everything is collected for payment. Updating a session charges nothing. When the campaign's designations list has more than one entry, record the donor's choice as designationId; the session state reports it under designation. Pass no designationId for a list with a single entry or an empty list.
