| 41 | * A Cloudflare account-owned API token (`POST /accounts/{account_id}/tokens`). |
| 42 | * |
| 43 | * Account-owned tokens are managed at the account level and persist |
| 44 | * independently of any single user. Use these for CI tokens, third-party |
| 45 | * integrations, or anywhere the token should outlive an individual user's |
| 46 | * session. |
| 47 | * |
| 48 | * Creating account-owned tokens requires the caller to have the |
| 49 | * `API Tokens > Write` account permission. |
| 50 | * ### Creating a Token |
| 51 | * **Example:** A token for managing Workers and KV from CI |
| 52 | * ```typescript |
| 53 | * // the account ID resolves from the profile you're deploying with |
| 54 | * const { accountId } = yield* yield* Cloudflare.CloudflareEnvironment; |
| 55 | * |
| 56 | * const token = yield* Cloudflare.ApiToken.AccountApiToken("ci-token", { |
| 57 | * name: "my-ci-token", |
| 58 | * accountId, |
| 59 | * policies: [ |
| 60 | * { |
| 61 | * effect: "allow", |
| 62 | * permissionGroups: [ |
| 63 | * "Workers Scripts Write", |
| 64 | * "Workers KV Storage Write", |
| 65 | * ], |
| 66 | * resources: { [`com.cloudflare.api.account.${accountId}`]: "*" }, |
| 67 | * }, |
| 68 | * ], |
| 69 | * }); |
| 70 | * |
| 71 | * yield* GitHub.Secret("cf-api-token", { |
| 72 | * owner: "me", |
| 73 | * repository: "my-repo", |
| 74 | * name: "CLOUDFLARE_API_TOKEN", |
| 75 | * value: token.value, |
| 76 | * }); |
| 77 | * ``` |
| 78 | * |
| 79 | * ### Attaching Policies via Bindings |
| 80 | * **Example:** Let a downstream capability contribute its own policies |
| 81 | * A token can be created with no `policies` of its own; the policies are |
| 82 | * supplied through its binding contract (see {@link ApiTokenBinding}). This is |
| 83 | * how capabilities like {@link CreateTunnel} provision a least-privilege token. |
| 84 | * ```typescript |
| 85 | * const token = yield* Cloudflare.ApiToken.AccountApiToken("scoped-token"); |
| 86 | * |
| 87 | * yield* token.bind("MyCapability", { |
| 88 | * policies: [ |
| 89 | * { |
| 90 | * effect: "allow", |
| 91 | * permissionGroups: ["Cloudflare Tunnel Write"], |
| 92 | * resources: { [`com.cloudflare.api.account.${accountId}`]: "*" }, |
| 93 | * }, |
| 94 | * ], |
| 95 | * }); |
| 96 | * ``` |
| 97 | * |
| 98 | * ### Exposing a Token to a Worker |
| 99 | * **Example:** Read the token value at runtime |
| 100 | * Bind the token's outputs in the Worker's Init phase to get runtime |
| 101 | * accessors. Binding `token.value` injects it as a `secret_text` Worker |
| 102 | * binding; the returned accessor reads it back (as `Redacted`) at runtime. |
| 103 | * ```typescript |
| 104 | * // init |
| 105 | * const value = yield* token.value; // Accessor<Redacted<string>> |
| 106 | * const accountId = yield* token.accountId; // Accessor<string> |
| 107 | * |
| 108 | * return { |
| 109 | * fetch: Effect.gen(function* () { |
| 110 | * const apiToken = yield* value; // Redacted<string> |
| 111 | * // ... call the Cloudflare API with `apiToken` |
| 112 | * return HttpServerResponse.text("ok"); |
| 113 | * }), |
| 114 | * }; |
| 115 | * ``` |

| 118 | * @product API Tokens |
| 119 | * @category Account & Identity |
