A CLI tool for interacting with the SendBlocks platform.
See our developer documentation for a more in-depth introduction.
npm install --global sendblocks-cliFor usage instructions:
sb-cli -hNOTE: For direct execution using npx, wherever the usage (or this documentation) says sb-cli, use sendblocks-cli instead.
For usage instructions:
npx sendblocks-cli -hUse the init command to initialize the project, this will configure your folder (or a folder you've provided as an argument) for use with the sendblocks-cli tool as well as initialize it with a sample functions.yaml configuration which will deploy an echo function.
IMPORTANT NOTE: If you're trying to initialize a project that's already got files in it, ensure that the files listed are safe before proceeding!
$ sb-cli init
Initializing project at /workspaces/test ...
Folder is not empty! Force initialization?
The following files will be modified / overwritten:
/workspaces/my_project/.gitignore,
...
? Are you sure you want to continue with the project initialization? › (y/N)Once your project has been initialized, you will be able to sign in to the SendBlocks API. For this you will require a client ID and secret, if you don't already have them then please get in touch with us!
If you have your credentials, sign in using sb-cli login and the token will be stored in the .auth of your project's root folder as well as printed to your console.
$ sb-cli login
✔ Enter your SendBlocks Client ID … 12ab3456-abab-1a23-a123-abcdef123456
✔ Enter your SendBlocks Secret … ************************************
Successfully logged in! Bearer token stored in .auth file.
Bearer token: eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6IjFmNjQ4NmJMIn0....Once you have successfully logged in, you will be able to refresh your authentication token with sb-cli login --refresh.
If your refresh token has expired, simply run sb-cli login again.
For more details on constructing valid webhooks, see Create Webhook in our API reference.
For more details on constructing valid functions, see Create Function in our API reference.
When a function is contained within a single file, use the code field, and it will be uploaded as-is and editable directly via the UI.
When a function's code is spread over multiple files and folders, use the source field to point to the function's root folder. A valid source folder must include exactly one entrypoint, either main.ts or main.js, and the entrypoint must include exactly one function handler called triggerHandler.
As there are limitations to the size of the bundled files that can be uploaded, if any component of your code needs to be generated then it is recommended to keep your source and distribution code separate.
After initializing your project, you will find a src/samples.yaml resource definition file along with a samples folder.
The sample resource definition file includes a function and its webhook. It is worth noting that the sendblocks-cli tool identifies functions and webhooks by name, in contrast to the SendBlocks API which relies exclusively on function and webhook UUIDs.

webhooks:
- echo_function_webhook:
url: https://your.webhook.url.here
secret: "auth secret"
functions:
- echo_function:
chain_id: CHAIN_ETH_SEPOLIA
code: samples/echo/echo_function.ts
is_enabled: true
should_send_std_streams: true
triggers:
- type: TRIGGER_TYPE_ADDRESS
address: "0x1234567890abcdef1234567890abcdef12345678"
locations:
- trace_from
webhook: echo_function_webhook
The echo_function sample points to samples/echo/echo_function.ts, which is a simple function defined in a single file that simply relays its context and data objects to its webhook.
export function triggerHandler(context: any, data: any) {
return { context: context, data: data };
}To deploy your changes, run sb-cli deploy. This will process all of the yaml files in the src folder and display a preview of the changes, requiring confirmation prior to deploying.

└─────────┴──────────────────────────┴────────────────────────────────────────┴──────────┴─────────┴──────────┘In order to backfill your subgraphs (or to trigger your functions for specific blocks for any other reason), you can use the sb-cli functions replay-blocks command.
The required arguments are --start <start_block_number> and --end <end_block_number>.
To specify functions to be triggered, provide a comma-separated list of function names with the --functions argument.
If no function names are provided, all deployed functions that are referenced in the YAML spec will be triggered (where relevant, assuming that the blocks are valid blocks for the functions' chains and that the blocks in the given range match the functions' triggers).
To destroy the resources described by your yaml files, run sb-cli destroy. This will not affect any resources that are not named in your resource definitions.
