Polling

Polling is a good fit when you want a periodic reconciliation job (for example, every 1-5 minutes) and can tolerate some delay compared to webhooks.

Poll until wallet is ready

After creating a wallet, poll GET /v2/wallets/{id} every 1-2 seconds until status !== "creating":

cURL

while true; do
  STATUS=$(curl -s "$BASE_URL/v2/wallets/$WALLET_ID" \
    -H "Authorization: Bearer $GROUND_API_KEY" | jq -r .status)
  if [ "$STATUS" = "idle" ] || [ "$STATUS" = "failed" ]; then break; fi
  sleep 1.5
done

async function waitUntilReady(walletId, apiToken) {
  while (true) {
    const res = await fetch(`${BASE_URL}/v2/wallets/${walletId}`, {
      headers: { Authorization: `Bearer ${apiToken}` },
    });
    const wallet = await res.json();
    if (wallet.status === "idle") return wallet;
    if (wallet.status === "failed") {
      throw new Error(`wallet ${walletId} failed: ${wallet.failureReason}`);
    }
    await new Promise((r) => setTimeout(r, 1500));
  }
}

import time, requests

def wait_until_ready(wallet_id, api_token):
    while True:
        r = requests.get(
            f"{BASE_URL}/v2/wallets/{wallet_id}",
            headers={"Authorization": f"Bearer {api_token}"},
        )
        wallet = r.json()
        if wallet["status"] == "idle":
            return wallet
        if wallet["status"] == "failed":
            raise RuntimeError(f"wallet {wallet_id} failed: {wallet['failureReason']}")
        time.sleep(1.5)

List wallets

cURL

curl -X GET "$BASE_URL/v2/wallets?limit=25" \
  -H "Authorization: Bearer $GROUND_API_KEY"

cURL

curl -X GET "$BASE_URL/v2/wallets?limit=25&cursor=$NEXT_CURSOR" \
  -H "Authorization: Bearer $GROUND_API_KEY"

Get a single wallet

cURL

curl -X GET "$BASE_URL/v2/wallets/$WALLET_ID" \
  -H "Authorization: Bearer $GROUND_API_KEY"

List deposits

cURL

curl -X GET "$BASE_URL/v2/wallets/$WALLET_ID/deposits?limit=50" \
  -H "Authorization: Bearer $GROUND_API_KEY"

Activity feed

The activity endpoint provides a unified, reverse-chronological feed of customer-visible deposits, withdrawals, and rebalances. Use scope=all for organization-wide activity, or pass one or more walletId parameters to filter to specific wallets.

cURL

curl -X GET "$BASE_URL/v2/activity?walletId=$WALLET_ID&limit=20" \
  -H "Authorization: Bearer $GROUND_API_KEY"

Query parameters:

Param	Description
`limit`	Max items per page. Runtime clamps invalid, missing, and oversized values into the supported 1-100 range.
`cursor`	Opaque cursor from `nextCursor` for pagination
`walletId`	Optional repeatable wallet ID filter.
`scope`	Optional `all` for organization-wide activity.
`type`	Optional type filter: `deposit`, `withdrawal`, or `rebalance`
`status`	Optional comma-separated status filter: `created`, `processing`, `completed`, `partially_completed`, `failed`, `cancelled`, or `all`
`startAt`	Optional inclusive ISO-8601 UTC lower bound for activity timestamps.
`endAt`	Optional exclusive ISO-8601 UTC upper bound for activity timestamps.

To poll only active wallet work, use:

curl -X GET "$BASE_URL/v2/activity?walletId=$WALLET_ID&status=created,processing&limit=20" \
  -H "Authorization: Bearer $GROUND_API_KEY"

Pass a non-null nextCursor as cursor to fetch the next page. See API Conventions for the list envelope.

Field	Description
`data`	Activity items for the current page.
`data[].id`	Unique ID for the activity parent
`data[].type`	`"deposit"`, `"withdrawal"`, or `"rebalance"`
`data[].status`	Public status: `created`, `processing`, `completed`, `failed`, or `cancelled`
`data[].amountUsd`	Amount as a fixed-precision decimal string (6 decimal places)
`data[].timestamp`	ISO-8601 timestamp of when the activity occurred
`data[].deposit`	Present for deposit rows
`data[].withdrawal`	Present for withdrawal rows
`data[].rebalance`	Present for rebalance rows
`nextCursor`	Opaque cursor for the next page, or `null`

List withdrawals

Filter by status to monitor in-flight withdrawals:

cURL

curl -X GET "$BASE_URL/v2/wallets/$WALLET_ID/withdrawals?status=processing&limit=50" \
  -H "Authorization: Bearer $GROUND_API_KEY"

const res = await fetch(
  `${BASE_URL}/v2/wallets/${WALLET_ID}/withdrawals?status=processing&limit=50`,
  { headers: { Authorization: `Bearer ${GROUND_API_KEY}` } },
);

console.log(await res.json());

import requests

res = requests.get(
    f"{BASE_URL}/v2/wallets/{WALLET_ID}/withdrawals",
    params={"status": ["processing"], "limit": 50},
    headers={"Authorization": f"Bearer {GROUND_API_KEY}"},
)

print(res.json())

Deposit address readiness

Read GET /v2/wallets/{id} until the intended network’s address appears in depositAddresses. Already returned addresses remain usable while others are being prepared. New wallets prepare Stellar automatically. Poll until depositAddresses.stellar_testnet appears in sandbox or depositAddresses.stellar appears in production. Other returned addresses are usable while Stellar setup continues. Show an address-setup indicator while provisioning continues. If the intended address is absent and setup returns failed, contact Ground. See Address readiness for funding steps and Supported Chains for network keys.
