To unstake ATOM tokens, you will need:

- The `delegator_address` from which ATOM was delegated, which will sign the transaction.
- The `validator_address` from which ATOM is being undelegated.
- The amount of ATOM to be undelegated.
- An optional memo to identify the transaction.
- An optional `gas_limit` and `gas_price` in ATOM.
- The pubkey (public key) of the `delegator_address`.

In the following guide we will illustrate how to unstake ATOM.

# Create New Unstaking Flow

To initiate the unstaking process with Staking API, create a new flow with `POST /flows`.

### URL

`https://api.figment.io/flows`

### Request

- `protocol`\* : `string` Protocol this flow operates on (ex. `cosmos`).
- `network`\* : `string` Network this flow operates on (ex. `testnet`).
- `operation`\* : `string` The operation to perform (ex. `unstaking`).

JSON

```json
{
  "protocol": "cosmos",
  "network": "testnet",
  "operation": "unstaking"
}
```

### Response

- `id` : `string` ID of the flow.
- `operation` : `string` The Staking API operation being performed by this flow.
- `state` : `string` The current state of the flow.
- `actions` : `array` It includes the `name` & `inputs` of all next possible actions.

- `create_undelegate_tx`: Use this action to generate an undelegation transaction to unstake your ATOM.

- `delegator_address` : The address from which ATOM was delegated.
    - `validator_address` : The validator address from which ATOM will be undelegated.
    - `amount` : The amount of ATOM to be undelegated.
    - `memo` : an optional message to record on-chain with your transaction.
    - `gas_limit`: the total amount of gas you're willing to let this transaction consume.
    - `gas_price`: how many ATOM you're willing to pay per unit of gas consumed by this transaction.
    - `pubkey` : Pubkey value will be retrieved from the chain but if you're using a fresh account (that does not have any outgoing activity) then this information is not available and it requires the user to pass it.
- `data` : `object` Flow & transaction data.

# Submit Undelegate Data

After creating the new undelegation flow, we need to submit the undelegate data.

After collecting the required inputs as mentioned below, send a `PUT` request to `/flows/[:flow_id]/next` to proceed to the next step.

### URL

`https://api.figment.io/flows/[:flow_id]/next`

### Request

- `name`\* : `create_undelegate_tx`.
- `inputs`\* : `object`
  - `delegator_address`\* : `string` The address from which ATOM was delegated.
  - `validator_address`\* : `string` The validator address from which ATOM will be undelegated.
  - `amount`\* : `number` The amount of ATOM to be undelegated.
  - `memo` : `string` A message to record on-chain with your transfer.
  - `gas_limit` : `number` The total amount of gas you're willing to let this transaction consume.
  - `gas_price` : `number` How many ATOM you're willing to pay per unit of gas consumed by this transaction.
  - `pubkey` : `string` Required only if you're using a fresh account (that does not have any outgoing activity) else optional.

JSON

```json

# Submit Signed Undelegate Transaction for Broadcast

Before broadcasting the transaction, you must sign the `transaction_payload` you received in the previous step. After signing the transaction, send a `PUT` request to `/flows/[:flow_id]/next` and the Staking API will broadcast the transaction to the network.

### URL

`https://api.figment.io/flows/[:flow_id]/next`

### Request

- `name`\* : `sign_undelegate_tx`
- `inputs`\* : `object`
  - `transaction_payload`\* : Signed transaction payload from the previous step's response.
  - `signatures` : `array` of `object` The signatures array can be used **instead of sending a transaction payload** when the signing keys are kept in a custodial solution.

JSON

### Response

- `id` : `string` ID of the flow.
- `operation` : `string` The Staking API operation being performed by this flow.
- `state` : `string` The current state of the flow.

- `undelegate_tx_broadcasting` : Transaction broadcasting and waiting for confirmation.
  - `unbonding` : Transaction successfully broadcast and stake is subject to unbonding period.
  - `completed` : Unbonding period is complete and tokens are successfully unstaked.
- `actions` : `array` It includes the `name` & `inputs` of all next possible actions.
- `data` : `object` Flow & transaction data.
